To do so, choose one of the following options:</p><ul><li>Set the time on the mobile device to automatic date and time</li><li>Tap the synchronization button in the authenticator app to sync the time (not provided with every authenticator app)</li></ul><p>If you cannot get your authenticator app to generate working security codes, consider deactivating the two-factor authentication by using your 16-character Recovery Code, which you were given when you first set up two-factor authentication on your TeamViewer account. Then set up two-factor authentication once more, using another authenticator app if possible.</p><p><strong>📌Note:</strong> Make sure to save the new Recovery Code whenever you disable and re-enable two-factor authentication, as the Recovery Code will be different each time it is enabled.</p><p><br></p><h3 data-id="-2"></h3><h2 data-id="further-reading">Further reading</h2><p><a href="https://community.teamviewer.com/t5/Knowledge-Base/Two-factor-authentication-Activation-and-Deactivation/ta-p/66" rel="nofollow noreferrer ugc">Two factor authentication - Activation and Deactivation</a></p><p><a href="https://community.teamviewer.com/t5/Knowledge-Base/What-is-two-factor-authentication-for-your-TeamViewer-account/ta-p/4711" rel="nofollow noreferrer ugc">What is two-factor authentication for your TeamViewer account?</a></p> </article> </main>
