Can't Remember Apple Computer Password

The password you use to unlock 1Password is called your Master Password. It’s also the password that you use to sign in to 1Password.com if you have a 1Password account.

If you forgot your Master Password, follow the steps below to try to recover it. After you unlock 1Password, you can change your Master Password.

If you think you remember your Master Password

If you believe you know your Master Password, but it isn’t accepted, try these steps:

• Make sure you’re typing lowercase and uppercase letters correctly. If Caps Lock is turned on, the Master Password field shows a Caps Lock symbol ⇪.
• Try older passwords. If you’re able to unlock the app with your old password, you can then change your Master Password.
• Type your password in another app, like a text editor, so you can see that you’ve entered it correctly. Then copy and paste it into 1Password.
• If you have multiple vaults or 1Password accounts, try the other passwords.
• If your Master Password has spaces, try it with and without spaces.
• If your Master Password has accents or special characters, try it with and without them.

• If you use multiple languages, make sure you’re using the correct keyboard layout when you enter your Master Password.

If you don’t know your Master Password or it isn’t accepted

• never logged locally
• never known to us at 1Password
• only known to you
• the only way to decrypt your data

If you have 1Password on multiple devices, see if your Master Password works on the others. (If you have a 1Password account, don’t forget to try signing in on 1Password.com.)

If your Master Password works everywhere except one device, you should be able to start over on the device where it’s not working, and then sync your data from your other devices.
