No, we do not store your Master Password.
If you’ve forgotten your Master Password and you have a recovery code, you can go to “My Account” and use the recovery code to change your Master Password without losing any of your encrypted data. If you use the mobile app and have your Master Password linked to your fingerprint or Touch ID / Face ID, you can go to your mobile device to recover your Master Password via biometric authentication.
If you don’t have a recovery code and don’t have your Master Password linked to your fingerprint, you’ll have to go to “My Account” and reset it.
Be careful, resetting your Master Password will have some irreversible consequences as you won’t be able to decrypt any of the data that was encrypted before (including your passwords). Please only do this as a last resort.
To keep your data safe, we recommend that you do not share your Master Password with anyone nor write it down.
