Can I use a Gate authenticator without a phone?

Yes. Gate supports Google Authenticator and its own Gate Authenticator, and both work from the same standard secret key — so does any app that produces time-based codes (TOTP). The Authenticator extension generates them in Chrome from the key Gate shows.

How do I move Gate 2FA to a new phone?

If you kept the secret key, add it to the new app or the extension and nothing changes on Gate. If the old authenticator still works, unbind it in Security Center and bind it again with the new key. If it is lost, use “Security Reset” as described below. With the extension, export a backup or restore one of its automatic backups on the new computer and the codes carry on working. Each bind or unbind pauses withdrawals and P2P trading for 24 hours.

What if I lose access to my authenticator?

If you can still sign in, click “Security Reset” (gate.com/securityreset), complete the identity verification and submit the unbinding request; Gate reviews it within 24 hours and emails the result. If you cannot sign in, the reset has to start in the Gate app: tap “unable to verify?” on the verification code screen. The website does not accept reset requests without a login.

Why are my Gate withdrawals suspended after setting up 2FA?

It is Gate’s safety hold: withdrawals and P2P trading are suspended for 24 hours after Google Authenticator is bound or unbound, and after other security changes such as a new phone number, email or password. The hold lifts by itself.

Gate.io Authenticator App — Bind Google Authenticator for 2FA

Gate asks for the authenticator code at login, for withdrawals, for password changes and for other security operations — the moments when someone with your password could take the account or move your funds out. Gate also recommends it if text message codes often fail to arrive.

Bind Google Authenticator on Gate

Only one authenticator can be bound to a Gate account at a time. For security, Gate suspends withdrawals and P2P trading for 24 hours after you bind or unbind Google Authenticator — so set it up well before you need to move funds.

Sign in at gate.com on your computer.
Click “Profile” in the top-right corner and select “Security Center” from the menu (some Gate pages call it “Security Settings”).
Find “Google Authenticator” and click “Enable”.
Gate shows a secret key to copy. Leave that page open and add the account to the extension as described below — with the key, or with “Scan QR from screen” if a QR code is shown as well.
Back on Gate, enter the six-digit code from the extension, fill in anything else Gate asks for and click “Confirm”.

Gate’s own instructions

Add Gate to Authenticator

Install 2FA Authenticator from the Chrome Web Store and pin it to the toolbar, so its icon is one click away.
Leave the Gate page with the QR code open. Click the Authenticator icon, then “Add Account” → “QR Code” → “Scan QR from screen”.
The account appears in the list with a six-digit code that changes every 30 seconds. Rename it if you like — the name is only for you.
Go back to Gate and type the current code into the confirmation field. If it is about to expire, wait for the next one.
Gate confirms that two-factor authentication is on. From now on it will ask for a code when you sign in — click the extension icon and copy it.

No QR code, or it will not scan? Look for the option to enter a key manually on Gate’s setup screen, copy the key, and add it in the extension with “Add Account” → “Manual” → “Secret Key”.

Keep the Gate secret key safe

Gate’s help describes no backup codes for the authenticator. The secret key you copy during setup is what the codes are made from: kept on paper, away from this computer and as private as a password, it lets you add the account to any authenticator again — Gate notes that Google Authenticator and Gate Authenticator both work with the same key. If it is lost too, the way back is Gate’s security reset, reviewed within 24 hours.

The code is not accepted?

Most often the QR code changed: the website makes a new one each time its setup page is reloaded or opened again, so the account you added first no longer matches. Start the setup again, add the QR code that is on the screen now and type its code in straight away. Two entries for the same website? Use the newest. Other reasons: why codes are refused.

Typed the key in by hand? Paste it into the TOTP code generator and compare the code with the one in the extension. If they differ, the key was copied wrong — add the account again.
