Switching Phones Is More Than Just Logging In Again
Many people think all they need to do after getting a new phone is reinstall the Binance APP and log in. In reality, if you don't prepare in advance, you might not even get past the login step — your Google Authenticator is gone, your bound phone number has changed, and all security settings need to be re-confirmed. Worse, if you don't properly handle your old phone (like selling it without deleting the APP), you could create a security vulnerability.
This article walks you through every step before and after switching phones. If you don't have a Binance account yet, register through this link for fee discounts. Android users can directly download the official APP.
What to Do on Your Old Phone Before Switching
First: Migrate Google Authenticator
Open Google Authenticator on your old phone, tap the menu in the upper right > "Transfer accounts" > "Export accounts." The system generates a QR code. Install Google Authenticator on your new phone, select "Import accounts," and scan this QR code. All authenticator entries sync over.
If your Google Authenticator has cloud sync enabled (signed into a Google account), then simply signing into the same Google account on your new phone will automatically make your authenticator codes appear — no manual migration needed.
Second: Record Security Information
Confirm you can access the following: your Binance registration email password, your bound phone number can receive SMS normally, and what your anti-phishing code is (write it down).
Third: Check Your Bound Phone Number
If you're changing phone numbers along with your phone, make sure to update your Binance bound phone number while your old number still works. Path: APP > Security Center > Phone Verification > Modify. You'll need to receive a verification code on your old number to confirm.
Installation and Login on Your New Phone
Download the Binance APP on your new phone, making sure to get it from official channels. After installation, open the APP and log in with your email and password.
The system will require security verification. If you've successfully migrated your Google Authenticator, enter the verification code. You may also need email or SMS verification codes.
Since this is the first login from a new device, Binance may send a device confirmation email. Open the email and click the confirmation link, and the new device will be added to your trusted device list.
Security Checks After Successful Login
Don't rush to check prices or trade after logging in — go through your security settings first:
Check Device Management: Security Center > Device Management. Confirm the list only contains devices you're currently using. Delete the entry for your old phone. If you see an unrecognized device, change your password immediately.
Verify 2FA Status: Confirm that Google Authenticator, SMS verification, and email verification are all working properly. Run a test on the security verification page.
Check Anti-Phishing Code: Confirm your anti-phishing code is still active. When you receive a Binance email, check whether it contains your anti-phishing text.
Review Withdrawal Whitelist: If you enabled the withdrawal address whitelist feature, verify all addresses in the whitelist are yours.
Review API Keys: If you previously created API keys, confirm no anomalous keys exist.
Handling Your Old Phone
Handling your old phone properly is equally important:
If selling or giving away: Log out of the Binance APP first, then uninstall it. A factory reset to completely wipe all data is recommended. Also remember to remove the old device from Binance's device management.
If keeping as a spare: At minimum, log out of Binance and remove it from device management.
If your old phone was lost: Immediately go to Device Management in the Binance APP on your new phone and remove the old phone. Also check for any abnormal login records. If your old phone didn't have a lock screen password, change your Binance password immediately.
Handling Special Situations
Authenticator wasn't migrated before disposing of the old phone: You'll need to go through Binance's 2FA reset process. During login, select "Unable to get verification code," then follow the prompts to upload identity documents and complete facial recognition. Approval typically takes 1-3 business days.
Phone number also changed: Contact Binance support with identity documents to request a phone number change. This process may be slow and could take several days.
Email also inaccessible: This is the most complex situation. You'll need to contact support with as much identity documentation and account information as possible to verify you're the account owner.
All these operations should be performed in a secure network environment. Avoid operating your Binance account on public WiFi.
FAQ
Q: Does logging in on a new phone automatically invalidate the old phone's session? A: No, it won't automatically expire. Binance allows multi-device login. You need to manually remove the old device from device management to invalidate its session.
Q: Is there any difference when switching from iPhone to Android (or vice versa)? A: At the Binance level, there's no difference — the login process is the same. However, cross-platform migration of Google Authenticator requires using the export/import feature or cloud sync; it cannot be migrated through system-level tools like iCloud or Samsung backup.
Q: Will transaction history and watchlists still be there after switching phones? A: Transaction history is stored server-side and isn't affected by switching phones. Watchlists are partially stored locally and partially synced to the server, so you may need to reconfigure them.
Q: Can I trade during the 2FA reset period? A: During the reset review period, account functions are restricted — withdrawals are typically disabled, but some features (like viewing assets) may still be available. Specific restrictions follow Binance's actual prompts.
