Google has released the first update for Google Authenticator in years and it comes with the long-awaited feature of being able to move 2FA accounts between devices.

When securing online accounts, many sites offer a feature called 2-factor authentication (2FA), or as 2-step verification (2SV), which requires a user to scan a unique QR code on an authentication app.
