Frequently Asked Questions (FAQ)

To use the generator, insert your Base32 secret into the input field. The site will automatically generate the current one-time password (OTP), as well as the previous and next ones for convenience. You can copy the OTP by clicking on it. If you need a new secret, click "Create New Secret". For advanced options like changing the digest algorithm, digits, or period, click "Advanced Settings".

Two-Factor Authentication (2FA) is a security process where users provide two different authentication factors to verify themselves. This adds an extra layer of protection beyond just a password. 2FA is crucial because it significantly reduces the risk of unauthorized access. Even if a hacker obtains your password, they can't log in without the second factor, like an OTP generated by this tool.

Your secret is the key to generating your OTPs. If lost, you may lose access to accounts protected by 2FA. Always store it securely (e.g., in a password manager or encrypted note). Remember, secrets generated on this site disappear forever when you leave or refresh the page—nothing is stored here for your privacy.

Use strong, unique passwords for each account; enable 2FA wherever possible; avoid public Wi-Fi for sensitive activities; keep software updated; be cautious with phishing emails; use antivirus software; and regularly review account activity for suspicious behavior. These steps help protect against common threats like hacking and identity theft.

2FA makes it much harder for hackers to breach accounts. It protects against password guessing, credential stuffing, and phishing attacks. Even if your password is compromised (e.g., via data breach), the hacker needs the second factor to access your account, buying you time to change credentials.

No, this site does not store any data, secrets, or use cookies. All operations happen in your browser, and nothing is sent to servers. Your secret is lost upon refresh for maximum privacy. See our Privacy Policy for details.

Clicking on the QR code generates a PDF report containing your Base32 secret, advanced settings (digest, digits, period), creation timestamp, QR code for easy scanning into authenticator apps, and a link to reload the secret on OTP2FA.APP. This serves as a secure backup—print it and store in a safe or locked drawer. Unlike digital storage, a physical copy can't be hacked remotely, making it ideal for long-term 2FA secret preservation. Always keep backups offline to prevent unauthorized access. This feature enhances your security by providing a reliable way to recover your 2FA setup if digital copies are lost.
