In short
Losing the device with your authenticator app means you cannot produce codes and cannot log in. First look for the backup codes or recovery key you saved when you set it up — with those, you can recover on your own. Without them, you must apply through the operator's official channel for a reset after an identity check, which typically takes days.
Key points
- The backup codes issued at setup are the key — look for them first
- If your authenticator app uses cloud sync, a new device may be able to restore it
- A reset request requires identity verification, and withdrawals are usually suspended meanwhile
- Anyone offering to handle the reset for you is a scam; never hand over backup codes
Definition
Losing the device or app that generates your one-time 2FA codes, leaving you unable to supply the code required at login.
Start by searching. When you enabled 2FA, most services displayed backup or recovery codes and told you to save them. You probably printed them, stored them in a password manager, or filed them somewhere. If you find them, entering one in place of a code at login generally restores access. Most are single-use, so reissue a fresh set once you are back in.
Next, check whether your authenticator app itself can be restored. Some apps offer cloud sync tied to an account, or an export function for migration. Installing the same app on a new device and signing in with the same account can bring the settings back. Not every app has this, and some deliberately do not offer sync.
If the device is in your hands but broken or wiped, the situation is the same: with no restore path, the settings are gone. Conversely, if the old device still works, migrate now rather than later. Migration generally means disabling 2FA on the old device and setting it up again on the new one — 'How to set up two-factor authentication' has the steps.
If nothing else works, request a reset. Open the official app, or the official site from your own bookmark, and apply through the support channel to have 2FA removed. You will generally be asked to submit identity documents and answer additional questions. As an anti-fraud measure, withdrawals are typically restricted during the review and for a period afterwards. Budget for several days, and longer with some operators.
Once you are back, build in redundancy. Print the backup codes and keep them somewhere at home you will not lose. Where possible, register the authenticator on more than one device. A physical security key is another option — 'Two-factor authentication methods' compares the approaches.
Watch out for
- · Never show backup codes to anyone or enter them at a third party's request — they are themselves a way in
- · Anyone promising a same-day 2FA reset is a scam. A legitimate reset always involves identity checks and a waiting period
- · If someone claiming to be support DMs you during a reset request, ignore it. Real replies come back through the channel you used to apply
Frequently asked questions
I never saved the backup codes.
Apply for a reset through the operator's official channel. They will usually help after verifying your identity, though the documents and timescale vary. Never ask anyone offering to do it on your behalf.
