Your authenticator secret can generate future sign-in codes. Decide where to keep it with the same care you give other account credentials. This guide explains what 2FA Live ONLINE stores and what it cannot recover.
Choose the storage behavior you need
| Action | Where the key is used |
|---|---|
| Generate without saving or sharing | The browser calculates the current code. This action does not save the key to the server. |
| Save code | The key is sent over HTTPS and stored in your account’s server-side vault. |
| Create share link | The key is sent over HTTPS and stored on the server so it can produce current codes for the link’s holder. |
The generator has no advertising scripts. These help pages are on a separate website address and have no field for entering a secret or signing in. Only use the generator at https://2falive.live/ for those actions.
Create an account you can keep access to
Accounts use a username and password, with no email address. The username must be 3–32 characters, begin with a letter or number, and use only letters, numbers, dots, underscores, or hyphens. Usernames are not case-sensitive. Passwords must contain at least 12 characters.
Use a unique password that you do not reuse elsewhere. Save your username and password in a trusted password manager or another private place you can access independently of this site. There is no email reset or password-recovery feature. Do not assume that proving ownership of an external account will recover your 2FA Live ONLINE login.
After signing in, you can add an optional account label before saving. Use labels that let you tell work, personal, and test accounts apart. Avoid putting a password, backup code, or secret key in a label: a label can appear on a share page.
What server encryption does and does not mean
Saved authenticator keys and share secrets are encrypted on the server with AES-256-GCM. Passwords are stored as salted scrypt hashes rather than plain text. These measures reduce some storage risks, but they do not make the vault end-to-end encrypted.
The server keeps the encryption key separately from the database. Someone who obtains both can decrypt the saved authenticator secrets. The application has automated checks, but it has not had an independent security audit. Do not read the presence of HTTPS or encryption as a guarantee against every type of compromise.
Keep a second way into important accounts
Keep the original service’s recovery codes or another supported recovery method somewhere you can reach if this website is unavailable. Protect those recovery details too, and do not store your only copy inside the same account they are meant to recover.
Recovery options vary by provider. Google, for example, documents backup methods and its own recovery process in its two-step verification help. Use your account provider’s instructions for your actual account. 2FA Live ONLINE cannot restore access to another service.
Use the tool on a device you trust
- Check the address before pasting a secret. The correct generator uses HTTPS at 2falive.live.
- Remember that the key and current code remain visible. Close the page when finished and sign out on shared devices.
- Keep your browser and device updated, and review extensions that can read websites.
- Keep secrets and share links out of screenshots, public documents, analytics, and support messages.
- Use the public demo when you only want to test the interface.
Remove each kind of access separately
Deleting an entry under Saved codes removes it from your vault. Existing share links are separate records and remain active until they expire or you revoke them. Open Shared links and review them too. Revocation cannot take back a code that someone already copied.
If the permanent setup key itself was exposed, removing it from this website does not invalidate that key at the original service. Replace the authenticator setup through the original service, then update the places that use it. Read the share-link guide before choosing lifetime access, and the privacy notice for more detail on website processing.
