FAQ

Unfortunately not. EAuthenticator is only usable with Linux, macOS, and Windows. But you can find other Authenticator apps, especially open-source ones, on mobile app stores.

At the moment EAuthenticator doesn't provide syncing with either EAuthenticator on other computers or a mobile Authenticator apps. But you can add an account to more than one Authenticator app by yourself. On your account select the manual method and add the secret to all Authenticators. After that check that all pins are equal.

At the moment EAuthenticator doesn't provide syncing with either EAuthenticator on other computers or a mobile Authenticator apps. But you can copy your account file to every other computer by yourself. The location of your file depends on your operating system. The following shows the path:

• Linux: ~/.config/EAuthenticator/eauth.data
• macOS: ~/Library/Application Support/EAuthenticator/eauth.data
• Windows: C:\Users\YourUserName\AppData\EAuthenticator\eauth.data

If you replace the eauth.data file on your other computer you can use your accounts on both.

There can be several problems why authentication fails:

1. Check that your login credentials are correct. Some websites require that you proceed with two-factor authentication also if your credentials are incorrect. Then the authentication fails no matter if the EAuthenticator one-time password is correct or not.
2. EAuthenticator uses TOTP for the generation of one-time passwords. This requires the correctness of your computer's clock. You can check the clock within the EAuthenticator. Go to 'Settings', then click on the Button 'Check Time'. If the resulting message doesn't show 'Your clock is good enough', you must change the clock to the correct time in your operating system's settings.

Short answer. Your account data is protected with the AES-256 block cipher and CBC operation mode. This is normally a really strong protection. We also use the OpenPGP format (RFC 4880) to store your data. Nevertheless, it's only secure if you provide a strong password. Your data is encrypted by default but only with a default password. This isn't secure.

We also plan to provide a technical description of data encryption and storing in the future.

Unfortunately not. We don't provide a 32-bit version and we are not planning to do so. If you are comfortable with using npm and electron, you can compile it for yourself. More information can be found on GitHub.

We don't provide a version of EAuthenticator on the App Store. But it's super easy to install it from a .dmg file. Go to Downloads and follow the steps.

If you are comfortable with using npm and electron, you can compile it for yourself. More information can be found on GitHub. Else maybe your distribution has a package maintainer who is interested in package EAuthenticator.
