Every time you scan a QR code into Google Authenticator, the seed secret that generates your codes gets backed up to Google's servers. It doesn't have to work that way.
BeardAuth is a self-hosted TOTP authenticator. Same 6-digit codes. Same QR code standard. Works with every site that supports 2FA. The difference is where the secrets live.
2FA is supposed to protect you. But when your authenticator app is a black box run by a corporation, you've just moved the single point of failure somewhere you have no control over.
BeardAuth is deployed as part of the BeardPowered sovereign stack. Get in touch to get it set up on your infrastructure.
