With these mechanisms, users verify their identity through their password and an additional proof of identity, such as a security key or a passcode. <br /><br />Google Authenticator makes it easy to use 2SV on accounts. In addition to supplying only a password when logging in, a user also enters a code generated by the Google Authenticator app on their phone. This is a safer alternative, used by millions of users, compared to passcodes via text message.<br /><br />Users place their trust in Google Authenticator to keep their accounts safe. As a result, security is always a high priority. We made several explicit design decisions to minimize the attack surface while increasing the overall usability of the app. <ul> <li>We ensured that no data is sent to Google’s servers during the transfer -- communication is directly between your two devices. Your 2SV secrets can’t be accessed without having physical access to your phone and the ability to unlock it.</li> <li>We implemented a variety of alerting mechanisms and in-app logs to make sure users are aware when the transfer function has been used.</li> </ul> <br />You can find more information about the Google Authenticator and its usage guide <a href="https://support.google.com/accounts/?p=transfer_codes">here</a>.</div> <span itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://plus.google.com/116899029375914044550' itemprop='url'/> </span> </script> <noscript> <span class="byline-author">Posted by Dongjing He, Software Engineer; Teddy Katz, Software Engineer; Christiaan Brand, Product Manager</span><br /> <span class="byline-author"><br /></span> Today is World Password Day, and we found it fitting to release an update that'll make it even easier for users to manage Google Authenticator <a href="https://www.google.com/landing/2step/">2-Step Verification</a> (2SV) codes across multiple devices. We are introducing one of the most anticipated features - allowing users to transfer their 2SV secrets, the data used to generate 2SV codes across devices that have Google Authenticator installed. For instance, when upgrading from an old phone to a new phone. This feature has started rolling out and is available in the latest version (5.10) of Google Authenticator on Android.<div> <br /></div> <div class="separator" style="clear: both; text-align: center;"> <a href="https://1.bp.blogspot.com/-xHj2tPSVXx8/XrSaA73vDBI/AAAAAAAAB3M/vM3OK082G34kN8ekmoNAp2p65Cm__2T4ACNcBGAsYHQ/s1600/authenticator.gif" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="352" data-original-width="512" height="220" src="https://1.bp.blogspot.com/-xHj2tPSVXx8/XrSaA73vDBI/AAAAAAAAB3M/vM3OK082G34kN8ekmoNAp2p65Cm__2T4ACNcBGAsYHQ/s320/authenticator.gif" width="320" /></a></div> <div> <br /><br /><div style="text-align: center;"> <i>Transferring accounts from one device to another with Google Authenticator</i></div> <br />Using 2SV, 2-Factor Authentication (2FA) or Multi-Factor Authentication (MFA) is critical to protecting your accounts from unauthorized access. With these mechanisms, users verify their identity through their password and an additional proof of identity, such as a security key or a passcode. <br /><br />Google Authenticator makes it easy to use 2SV on accounts. In addition to supplying only a password when logging in, a user also enters a code generated by the Google Authenticator app on their phone. This is a safer alternative, used by millions of users, compared to passcodes via text message.<br /><br />Users place their trust in Google Authenticator to keep their accounts safe. As a result, security is always a high priority. We made several explicit design decisions to minimize the attack surface while increasing the overall usability of the app. <ul> <li>We ensured that no data is sent to Google’s servers during the transfer -- communication is directly between your two devices. Your 2SV secrets can’t be accessed without having physical access to your phone and the ability to unlock it.</li> <li>We implemented a variety of alerting mechanisms and in-app logs to make sure users are aware when the transfer function has been used.</li> </ul> <br />You can find more information about the Google Authenticator and its usage guide <a
