We recommend downloading Authy for two-factor authentication (2FA) on your Gemini account to enhance security and avoid potential vulnerabilities associated with SMS authentication.
To download the Authy app on your mobile device, visit their website here: Authy Creation page.
Note: Authy on Desktop is not supported on Gemini; you must use Authy’s mobile app to generate 2FA code for logins or to authorize withdrawals on your Gemini account.
When creating an Authy account, please ensure that you use the same phone number that is registered on your Gemini account. Once you open the Authy app, you will see a Gemini token loaded - there will be no need to scan a QR code.
For the highest level of security, we suggest disabling the multi-device option to further protect your Authy account. For more information on turning off multi-device, please click on the following link: Turning off Authy Multi Device.
