TwoFaBackup

Application to safely and locally store backup codes for two factor authenticated services. It is good pracice to store these codes in an other location than in e.g. the password manager that stores the first factor or in the authenticator app that generates the one time passwords.

The backup is locally stored in a sqlite database with symmetric Fermet encryption. The sqlite database stores a id, service name, description [optional], the backupcodes [encrypted], date added. A new encryption key will be generated when first codes are saved in the db. The location of the database is $HOME/.config/2FA_codes.db.

!! Do not lose the generated key, or your codes will be lost !!
