Generate time-based one-time passwords (TOTP) for compatible authenticator setups. Explore two-factor authentication guides, account security tips, and practical tools for safer online access.
Enter a compatible Base32 authenticator secret to generate a six-digit time-based authentication code in your browser.
Your secret is processed locally by this page. Avoid using untrusted websites with sensitive production credentials.
A two-factor authentication code generator creates a temporary verification code that can help protect an account beyond a password. Many authenticator applications use the Time-Based One-Time Password (TOTP) standard. These codes usually change every 30 seconds and are generated from a shared secret and the current time.
Generate six-digit TOTP codes using the standard HMAC-based time-based one-time password algorithm.
Follow the remaining validity window before the current time-based code expires and the next one becomes available.
Copy the generated code to your clipboard when supported by your browser and device security settings.
The generator processes the supplied secret in your browser. Do not assume that third-party scripts or browser extensions are safe merely because the page runs locally.

Two-factor authentication adds another verification step to the sign-in process. Depending on the service, the second factor may be an authenticator code, a security key, a device approval, or another supported method.

Do not share your authenticator secret with anyone. Some services use different algorithms, digit lengths, or time intervals, so not every verification code is compatible.

Read Guide →2FA stands for two-factor authentication. It requires two different types of evidence to verify a sign-in, such as a password and an authenticator code.
TOTP means Time-Based One-Time Password. It is a temporary code calculated from a shared secret and the current time.
Possible causes include an incorrect secret, device clock differences, an unsupported algorithm, an expired code, or a service that uses a different authentication method.
Standard TOTP generation requires the correct shared secret. A username or password alone is not enough to calculate the matching authenticator code.

An online generator can expose a secret to risks from website code, third-party scripts, browser extensions, or compromised devices. For sensitive accounts, use a trusted authenticator application or security key.
