Lost password for my 2FA application (Aegis Authenticator)

Hello,

For security, I use 2-factor authentication. (2fa) As 2fa app, I am using Aegis but unfortunately I lost my vault password. Indeed, to access my vault, I only used biometrics and little by little I forgot the written password!
The problem is that I just changed the fingerprint I use to unlock my phone and when I go back to the Aegis app I am asked to unlock my vault only with the password.
How can I recover my vault password or how can I regain access to websites that I have protected with my 2fa Aegis app?

Thank you very much for your ideas!

Are you asking about this Android app?

Seems like you have also asked on their bug tracker. This is not related to Fedora and the answer over there suffices.
