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. |
