TOTP 2FA 실시간
Base32 시크릿으로 TOTP 2FA 코드를 실시간 생성합니다. Google Authenticator·Authy·Microsoft Authenticator와 호환됩니다.
One secret per line. Accepted formats: plain Base32 (JBSWY3DPEHPK3PXP), labeled (GitHub: KZXW6YTBOI), or full otpauth:// URL.
These defaults apply to every line. otpauth:// URLs override them per entry.
Secrets stay in your browser. The HMAC signing happens with the Web Crypto API on this device. Nothing is uploaded.
