常见问题
What is TOTP?+
TOTP (Time-based One-Time Password) is the algorithm behind most two-factor authentication (2FA) apps. It combines a shared secret key with the current time to generate a 6-digit code that changes every 30 seconds.
Is this a replacement for Google Authenticator?+
This tool is designed for developers testing TOTP implementations, not as a daily 2FA app. For actual account security, use a dedicated authenticator app (Google Authenticator, Authy, 1Password) that securely stores your secrets.
