2FAS Auth is an easy-to-use authentication app that protects access to your online services and accounts.



Relying on a single password for your personal accounts, like Facebook or Instagram, often puts your data and sensitive information at risk.



The 2FAS Authenticator App generates one-time codes called Time-based One-time Passwords (TOTP) or HMAC-based (event-based) One-time Passwords (HOTP) for your account. By creating these codes offline and changing them every 30 seconds or every login, 2FAS drastically increases the security of your information.
