Frequently asked questions
Q: I forgot my password, can I recover my encrypted notes?
A: No. It is not possible to recover encrypted notes without the password.
Q: Can I recover my password? Where is it stored?
A: No. The plain-text password is never stored on the device or anywhere else at any given time and comes directly from user input when needed.
Q: How do you validate the password if password not being stored?
A: When you set the password, a one-way hash code of the password is generated stored on the device and used later for password validation.
Q: Can my notes be decrypted using this hash code of the password?
A: No. The hash code is only used for password validation and not for encryption.
Q: How does encryption with fingerprint work? I am not asked for the password if I use fingerprint, how do the password and fingerprint relate? Am I not using the password when I am using fingerprint?
A: Aha! You are still using the same password under the hood while using fingerprint authentication. Android stores fingerprint data in a trusted execution environment(TEE), which is secure and provides a hardware-backed Keystore. In FairNote, when you choose to use fingerprint for the first time, you are asked to provide the password, and the password then is encrypted using a key from the hardware-backed Keystore. Only your fingerprint can obtain this key, and the key in turn opens the encrypted password for use.
Q: How about auto encryption? I used another app that automatically encrypted notes after edit/exit, and I don't like being asked to provide password/fingerprint every time I make some change.
A: Auto encryption is not possible because auto encryption requires the plain-text password be present on the device for use. In FairNote, the password comes from either user input or fingerprint, so user intervention is required.
