2FA 코드 생성기

TOTP (Time-based One-Time Password) generates 6-digit codes that change every 30 seconds. It is the standard behind Google Authenticator, Authy, and most 2FA apps. Codes are computed from a shared secret key and the current time.

Dokall processes secrets entirely in your browser - nothing is sent to a server. However, any website where you enter a 2FA secret is a risk if the site is compromised. Prefer your dedicated authenticator app for daily use. Use this tool for recovery or testing.

Authenticator apps store a random secret encoded in Base32 (letters A-Z and digits 2-7). When you set up 2FA, the service shows this key as text or in a QR code. Dokall accepts the Base32 string directly or an otpauth:// URI.

The most common cause is clock drift. TOTP depends on synchronized time. Ensure your device clock is accurate (enable automatic time sync). Also verify you pasted the complete secret with no extra spaces.

Yes. Add multiple secret keys with optional labels. Each generates its own 6-digit code that refreshes every 30 seconds. Useful for managing backup codes or testing multiple services.
