A share link lets its holder view current codes without signing in to 2FA Live ONLINE. Treat the full link as sensitive access: someone who receives it can keep getting codes for as long as the link stays active.

The code timer and the link timer are different

The code timer tells you when the displayed number changes. The link expiry tells you when the viewer stops getting codes. A link that lasts one day can show many different short-lived codes during that day. Choosing Lifetime removes the link’s expiry; it does not freeze one code forever.

Share duration choices in 2FA Live ONLINE
ChoiceWhen access ends
1 hourOne hour after creation, or earlier if its signed-in owner revokes it.
1 day24 hours after creation, or earlier if its signed-in owner revokes it.
7 daysSeven days after creation, or earlier if its signed-in owner revokes it.
LifetimeNo automatic expiry. A signed-in owner can revoke it. A guest-created lifetime link cannot be revoked through the app.

Lifetime describes the expiry setting. It is not a promise that the website or a particular account will operate forever. The page also needs the service to be available to fetch its next code.

Create a link you can manage

  1. Sign in to 2FA Live ONLINE before creating the link if you need a revoke control later.
  2. Generate the intended code, or find its entry under Saved codes.
  3. Select Create share link or Share.
  4. Choose the shortest useful duration and select Create share link.
  5. Copy the full link before closing the dialog. Send it only to the intended authorized recipient.

The full link is shown once when created. The saved link list lets its signed-in owner see its status and revoke it; it cannot reveal the original full link again. If you lose the link, create a new one and revoke the old one if you no longer need it.

What the recipient can see

The viewer shows the current code, the account label, the refresh timer, and the link’s expiry. It does not display the permanent setup key. It also does not reveal your 2FA Live ONLINE password or list your other saved entries.

Hiding the setup key does not make a link harmless. It deliberately gives its holder access to the second-factor codes for that one authenticator. If the recipient forwards the link, the next holder can use it too. Use the original service’s own delegated access or team-member features when those better fit the task.

Revoke a link

Sign in to the account that created it, open Shared links, find the correct active link, and select Revoke. Confirm the action. The link stops providing new access. A code someone already copied may still be accepted for its current time window, depending on the original service.

Revoking one link leaves other links for the same authenticator active. It also leaves the saved authenticator in your vault. Conversely, deleting a saved authenticator does not revoke links you previously created for it. Review and revoke each unwanted link separately.

You can create a link without an account, but there is no signed-in owner to manage it later. Signing in afterward does not attach an earlier guest link to your account. Timed guest links end at their chosen expiry. Guest lifetime links have no expiry and no revoke control.

If an unrevokable link reaches someone who should not have access, use the original account provider’s security settings to replace the authenticator secret. Before changing that setup, make sure you have a working recovery method. A new secret requires updating every authenticator that was using the old one.
