TOTP Generator

使用方法

1. Paste your base32 TOTP secret into the secret field — typically found in an authenticator app's backup or QR code URI。
2. Click "Generate code" to produce the current 6-digit TOTP。
3. Read the code and note the remaining validity in seconds shown next to it。
4. The secret and code are never stored or sent anywhere — they stay in browser memory only。

範例

• Entering a valid base32 secret like JBSWY3DPEHPK3PXP generates a 6-digit code valid for up to 30 seconds, matching what Google Authenticator would show。
• If the secret contains non-base32 characters, an "Invalid base32 secret" error appears instead of a code。
