Setup steps
- 01
Open the security page
From your Binance account profile, open Security and choose the authenticator-app path.
- 02
Enable the authenticator
Choose Enable, then follow the Binance prompt to connect Google Authenticator or another TOTP app.
- 03
Scan the QR code
Scan the QR code or enter the manual secret in the authenticator app, then confirm the one-time code Binance asks for.
- 04
Save the backup key
Write down the Backup Key and store it offline before you submit the change.
Recovery and backup
Use the official reset flow
If you lose the authenticator, use the Binance support recovery or reset path shown in the security center.
Rebind only after access is restored
Do not remove the old authenticator until Binance confirms the new one is active.
Keep the phone number and email current
Binance recovery depends on the contact methods that remain attached to the account.
Common problems
Verify the domain
Open the support link or the in-account Security page directly, because phishing pages often copy authenticator setup screens.
SIM-swap risk
Avoid SMS as the main recovery method for a high-value crypto account.
Device replacement
When you move to a new phone, keep the old device until the new authenticator is tested and confirmed.
