Yoosee Login Failed? How to Fix Sign-In Errors in the App

When a Yoosee login fails and you are sure the password is right, the cause is usually not the password at all. The most common culprits are signing in with a different identifier than the one you registered (phone number versus email, or the wrong country code), an outdated app, a network that blocks the app from reaching the service, or a session that was ended because the same account signed in somewhere else. Work through the checks below in order; each one takes a minute and rules out a whole class of problems.

If you genuinely do not remember the password, skip ahead: the reset process is covered in what to do when you forgot your Yoosee password. This article is for everything else.

First, read the error message carefully

The wording on screen tells you which part of the chain broke. Exact messages differ by app version and language, but they fall into a few families:

• "Account does not exist" or "user not registered". The app cannot find the identifier you typed. This points to the wrong sign-in method or the wrong country code, not a wrong password.
• "Incorrect password" or "account or password error". The account was found, but the password did not match. Check for keyboard problems before assuming you forgot it.
• "Network error", "connection timed out" or a spinner that never finishes. The app never reached the service. Your credentials were not even checked yet.
• "Your account has logged in on another device" or a sudden return to the login screen. The session was ended from the server side. Your password still works.
• "Too many attempts" or "try again later". A temporary lock after repeated failures. Waiting is the fix; more attempts usually extend it.

Check 1: Are you using the identifier you registered with?

A Yoosee account is tied to whatever you used at sign-up: usually a phone number or an email address. The app does not treat them as interchangeable. If you registered with your phone number, typing your email address will report that the account does not exist, and the reverse is also true.

What to try:

1. Think back to the day you set the camera up. Did you receive a code by text message or by email? That tells you which identifier the account uses.
2. Look for the right tab or toggle on the login screen. On most app versions there is a choice between phone and email sign-in. It is easy to miss, and the app may remember whichever one you used last on a different account.
3. Try every address you own. People with a work and a personal email often registered with the one they no longer check.
4. If someone else set up the camera for you, such as an installer, a relative or the shop where you bought it, the account may be theirs, not yours. Ask them which identifier they used. If you want your own login rather than theirs, the cleaner long-term fix is to have the camera shared to your own account.

Check 2: The country code and phone number format

Phone-number logins fail surprisingly often because of formatting, not because the number is wrong.

• Select the correct country or region in the country code picker before typing the number. If the picker shows a different country from the one where you registered, the app looks for a different account.
• Do not type the country code twice. If the picker already adds it, enter the number without it.
• Leading zero. Many countries write local numbers with a leading zero that is dropped in international format. If one version fails, try the other: with the zero and without it.
• Bought the phone abroad or travelled since signing up? The app may default the country picker to your current location. Set it back to the country of the number you registered.

If the message changes from "account does not exist" to "incorrect password" after you fix the format, you have found the account and can move on to the password checks.

Check 3: Rule out keyboard and autofill problems

Before you reset anything, make sure the password you think you are typing is the password the app receives.

• Tap the eye icon to show the password and read it character by character.
• Watch for automatic capitalisation. Many phone keyboards capitalise the first letter of a field without asking.
• Check the keyboard language. A keyboard set to a different language or layout can swap characters, add accents, or replace symbols.
• Look for a trailing space. Pasting from a notes app often brings one along.
• Turn off autofill for a moment. A password manager or the phone's own autofill may be inserting an old saved password for this app. Type it by hand instead.

If it still says the password is wrong after all of this, and you have changed it recently on another device, the new password is the one that counts. If you cannot remember either version, use the reset route in the password recovery guide.

Check 4: Update the Yoosee app

An old version of the Yoosee app can fail to sign in even when everything you type is correct, because the service may stop accepting requests from versions it no longer supports. The symptom is often vague: a generic error, a login button that does nothing, or a crash right after you tap it.

1. Open Google Play or the App Store and search for the app.
2. If an Update button appears, install it.
3. After updating, force close the app and open it again before you retry.

If the problem started right after an update, the opposite can also happen: a fresh version may need permissions the old one did not. Accept the permission prompts when you open it, then try again.

Check 5: Network problems that look like login failures

The login request has to reach the service. If it cannot, the app may show a network error, or it may show something that looks like a credentials problem. Rule the network out in this order:

1. Switch from Wi-Fi to mobile data, or the other way round, and try once. If it works on one and not the other, the network is the problem, not your account.
2. Turn off any VPN or proxy on the phone. Some VPN routes are blocked or slow, and some send your traffic through a different region, which can confuse location-based defaults.
3. Avoid networks with a sign-in page, such as hotel, café or guest networks. Until you accept their terms in a browser, the app cannot get through.
4. Office and school networks often block the connections camera apps use. Test on a phone hotspot to confirm.
5. Check the phone's date and time. Secure connections can fail if the clock is far off. Set date and time to automatic in the phone's settings.

Check 6: Clear the app's stored data, or reinstall

Sometimes the app keeps a corrupted login state that survives a restart.

• On Android: open Settings, go to Apps, find the app, then Storage, and clear the cache. If that does not help, clear the storage or data as well. This removes saved logins on the phone only; it does not touch your account or your cameras.
• On iPhone: there is no cache button, so delete the app and reinstall it from the App Store.

After reinstalling you sign in again, and your cameras reappear because they belong to the account, not to the phone. You may be asked for each camera's device password again, so have it to hand.

When the verification code never arrives

Registering, resetting a password, and sometimes signing in on a new phone all depend on a code sent by text message or email. If it does not show up:

• Wait a few minutes before tapping resend. Repeated requests often trigger a cooldown, and the later codes may make the earlier ones invalid. Use only the most recent code.
• For email: check the spam, junk and promotions folders, and search your mailbox for the app name.
• For text messages: check whether your phone filters messages from unknown senders into a separate folder; both Android and iPhone can do this, depending on your settings.
• Check the number or address on screen before requesting the code. A typo here sends the code somewhere you will never see it.
• Roaming or a new SIM. If you are abroad, some networks do not deliver short-code messages while roaming. If you changed numbers, the code goes to the old one, and self-service recovery will not work.
• Try the other channel if both a phone number and an email are linked to the account.

If none of this works, the realistic options are the app's own feedback or support function and the seller you bought from. Expect to be asked to prove the account or the camera is yours.

Logged out by another device

If the app suddenly returns to the login screen with a message about another device, your account has been signed in somewhere else. Whether more than one phone can stay logged in at the same time depends on the app version, and some versions send alerts only to the most recent login.

What to do:

1. Sign back in on the device you want to use.
2. Think about who else knows the password. A partner, an employee, an old tablet, or a computer running the PC client can all end your session when they sign in.
3. If you do not recognise the other sign-in, change the account password straight away. On most app versions this signs out other devices, which is what you want if someone you did not authorise has it; sign in again on your own devices afterwards.
4. Stop sharing one login between people. Give each person their own account and share the cameras to them. Nobody kicks anyone else out, and you can remove a person without changing your password.

Yoosee login on a PC

The same rules apply when you sign in on a computer: use the identical identifier, the same country code, and the same password as on your phone. Two extra things cause most failed attempts on a desktop:

• The firewall prompt. If you blocked the program when Windows asked, it cannot reach the service, and sign-in fails without a clear reason. Allow it on private networks in your firewall settings.
• A second account created by accident. If you registered again from the computer, you now have an empty account. The login works, but no cameras appear.

If you are still choosing how to watch on a computer, the PC client and emulator options are compared in detail, including which features carry over.

Signed in, but no cameras appear

A successful login with an empty device list is a different problem from a failed login, but people often report it the same way.

• You are in the wrong account. This is the most frequent reason. Sign out and try your other email or phone number.
• The camera was shared to you and the share was removed. The owner has to share it again.
• The camera was never added under this account. Someone else set it up under theirs. Ask them to unbind it, or factory reset the camera and add it to the app again under your own account.
• The cameras appear but stay offline. That is a connection problem on the camera side, and the offline checklist is the place to start.

When to get help

Stop troubleshooting on your own and contact support through the app, or the seller, if:

• the app says the account does not exist and you have tried every identifier and country code you could have used;
• you no longer have access to the phone number or email the account was registered with;
• you suspect someone else has taken over the account and changed its password or contact details;
• the app reports that your account is locked or restricted, and waiting has not cleared it.

Frequently asked questions

Why does the Yoosee app say my account does not exist?

The app cannot find an account for the exact identifier you typed. Usually you registered with a different method, such as phone instead of email, or the country code or number format does not match what you used at sign-up. Try the other sign-in tab and both versions of your phone number before assuming the account is gone.

Can I log in to Yoosee without a phone number?

On most app versions you can register and sign in with an email address instead of a phone number. If your existing account was created with a phone number, though, you need that number to sign in to that account. Menu labels vary slightly by app version, so look for a phone and email choice on the login screen.

Will reinstalling the app delete my cameras or recordings?

No. Reinstalling only removes data stored on the phone. Recordings on the camera's memory card stay on the card, and the camera list comes back once you sign in to the same account, so make sure you know which identifier that is before you uninstall.

Why do I keep getting logged out of the app?

Most often another phone, tablet or PC client is signing in to the same account. If the logouts happen without any message, check whether battery-saving settings are closing the app in the background, and exclude the app from battery optimisation to see if it stops.
