Configuring Two-Factor Authentication
Two-Factor authentication is highly recommended as a security precaution against unauthorized access to your account. Blesta supports both MOTP and TOTP. The following mobile applications are recommended for Android and iOS, respectively, and many others are supported as well.
- Android Token - http://code.google.com/p/androidtoken/
- Google Authenticator - https://play.google.com/store/apps/details?id=com.google.android.apps.authenticator2&hl=en
For iOS (iPhone, iPad)
- OATH Token - http://itunes.apple.com/us/app/oath-token/id364017137?mt=8
- Google Authenticator - https://itunes.apple.com/us/app/google-authenticator/id388497605?mt=8
As of Blesta 3.1, a QR code may be scanned from Google Authenticator to set it up. If you are running an earlier version of Blesta, continue reading.
Using Google Authenticator with Blesta is pretty straight forward, but requires a little manipulation to get the key in the correct format. Blesta expects TOTP keys to be in hexadecimal format (base16), but Google Authenticator uses base32. So we have to convert our Google Authenticator keys into hexadecimal before storing in Blesta.
There are a number of online utilities to perform this operation. Here’s one:http://www.darkfader.net/toolbox/convert/.
As an example, “PEHMPSDNLXIOG65U” (in base32) becomes “790ec7c86d5dd0e37bb4″ in hexadecimal. Simply select Time-based One Time Password as the two factor authentication method in Blesta then enter the converted (hexdecimal) value and you’re good to go.

- If you follow the instructions provided by yubico you will need to convert your Google secret key from base32 into hexadecimal (base16) format before adding it to Blesta. Instructions on doing that are provided in the note above.
To set up Two-Factor Authentication, visit the "My Info" link at the top of any staff page.
If you have access to add additional Staff, you can set up Two-Factor Authentication at account creation under [Settings] > [System Settings] > Staff.
Help! I've lost the token to my Staff account. How can I disable Two-Factor Authentication?
If you are locked out of Blesta because you lost your 2FA token, you must disable Two-Factor mode in the database for your user. To do so, you must make a change manually to the database using a utility like phpMyAdmin. Find your user in the "users" table, and update users.two_factor_mode to none, and save. You will now be able to login with just your username and password. Once you have logged in, you can set up 2FA again under My Info.
