How to transfer Google Authenticator codes to a new phone

Step 1: Put the old and new phone side by side

• Have both phones ready: the old one with your codes and the new one.
• Install Google Authenticator on the new phone. After an iPhone transfer the icon may be there, but you have to tap it to download the app.

Step 2: On the new phone, choose Scan a QR code

• Open Google Authenticator on the new phone. It shows no codes yet.
• On Set up your first account, tap Scan a QR code. That's the easiest way.
• Allow the camera when asked and tap OK.

Step 3: On the old phone, open Export accounts

• In Google Authenticator on the old phone, tap the menu at the top right.
• Choose Export accounts and tap Continue.
• Confirm with Face ID.

Step 4: Pick the accounts and show the QR code

• All accounts are selected. You can also pick only some of them.
• Tap Export. The old phone shows a QR code.

Step 5: Scan each QR code, then tap Next

• Point the new phone at the QR code and tap Continue.
• On the old phone tap Next to show the next code, and scan it too.
• With many accounts there are several codes. Here it was 9 (“Scan QR code 2 of 9”).

Caution: Keep going until the last QR code is scanned. Otherwise some accounts won't move.

Step 6: Confirm the accounts were imported

• After the last code, the new phone says the accounts were imported.
• Tap OK. Your codes now show in Google Authenticator on the new phone.

Step 7: Decide what to do with the old phone

• Tap Next on the old phone. It offers to remove the exported accounts.
• In the video this was skipped, because the old phone was going to be erased anyway.
