Authenticator apps generate time-based one-time passwords (TOTP) that change every 30 seconds. When you log in, the app and the server both generate the same 6-digit code based on a shared secret key. This adds an extra layer of security because even if someone knows your password, they can't access your account without the code from your authenticator app.
FAQs & Answers
- How does an authenticator app increase security? Authenticator apps increase security by generating time-based one-time passwords (TOTP) that change every 30 seconds, ensuring that even if someone has your password, they cannot access your account without the current code from the app.
- What is a time-based one-time password (TOTP)? A time-based one-time password (TOTP) is a temporary numeric code that is generated by an authenticator app based on a shared secret key and the current time, changing every 30 seconds to enhance security.
- Do I need an internet connection to use an authenticator app? No, you do not need an internet connection to use an authenticator app. The app generates codes based on an internal clock and the shared secret, allowing you to access your accounts even offline.
- What happens if I lose my phone with the authenticator app? If you lose your phone, you may not be able to access your accounts protected by the authenticator app. It is crucial to have backup recovery codes or a secondary authentication method set up to regain access.
