2FA Authenticator SL is a local-first authentication application. Your authenticator accounts, saved passwords, and app settings are stored locally on your device.
The app does not require you to create an account. We do not collect your name, email address, phone number, or identity information.
Your 2FA accounts and password vault data are stored locally and protected using encryption provided by the device. Your data is not uploaded to our servers.
The app can create encrypted backup files. Backup files may contain your authenticator accounts and saved passwords depending on your selected backup option. You are responsible for keeping your backup file and backup password safe. A forgotten backup password cannot be recovered.
If enabled, Android Autofill allows the app to provide saved login information to supported applications and websites. This feature only works with data stored locally in your password vault.
We do not sell, share, or transmit your stored authentication data or passwords.
