Gemini is required by law to collect your phone number to comply with local regulations and licensing requirements.

Additionally, your cell phone number can be used to set up two-factor authentication (2FA). 2FA adds an additional layer of security to your account by requiring a second form of verification (such as a code sent via SMS) in addition to your password. This helps protect your account from unauthorized access.

If you would like to change the phone number linked to your Gemini account, please review this article. To learn more about how we safely and securely store this information, please refer to this page this page.
