What is Get2FA.dev?
Get2FA.dev is a focused utility for generating time-based one-time passwords (TOTP), the six-digit codes commonly used by authenticator apps. It supports a single secret or a bulk list when you need to check several accounts at once.
The tool is designed to be fast, clear, and available without creating an account. It uses the standard time-based method used by many services that offer app-based two-factor authentication.
Why we built it
Sometimes you need a temporary, browser-based way to generate a TOTP code: while testing an integration, recovering a workflow, or working with several authorized accounts. Get2FA.dev provides that narrow function without turning it into a larger account-management product.
Privacy by design
TOTP calculations happen in your browser. The secret keys entered into the generator are not intentionally submitted to our application server, stored in our database, or sent to DeepL. Clearing the form or closing the page removes them from the tool state.
Your browser environment, device extensions, network, and the service you are signing in to remain outside our control. For high-value accounts, a reputable offline authenticator or hardware security key is usually the safer long-term choice.
What the tool supports
- Standard Base32 TOTP secrets.
- Single-code generation with a visible countdown.
- Bulk generation for multiple authorized secrets.
- Light and dark display modes.
- Public content in multiple languages.
Responsible use
A TOTP secret can be used to generate future authentication codes. Treat it like a password: only use secrets you own or are authorized to manage, never send one through the contact form, and avoid entering sensitive secrets on a shared or untrusted device.
