# Global AI Personal Settings: Profile, 2FA, and Passkey

> Update your Global AI profile: change username and password, bind email, enable two-factor authentication, register a Passkey.

Personal settings manages account details and sign-in security. Click **Profile** in the left sidebar, or go directly to [https://globalai.vip/profile](https://globalai.vip/profile).

## Update basic information

<Steps>
  <Step title="Change username">
    In the **Personal info** section, click the edit button next to your username, enter a new username, and save.
  </Step>

  <Step title="Change password">
    In the **Security** section, click **Change password**. Enter your current password, then the new password, and confirm. Sessions on other devices are invalidated after the change.
  </Step>

  <Step title="Bind or change email">
    In the email section, click **Bind** or **Change email**. Enter the email address, click **Send verification code**, and submit the code you receive.
  </Step>
</Steps>

<h2 id="enable-two-factor-authentication-2fa">
  Enable two-factor authentication (2FA)
</h2>

Two-factor authentication adds a second layer beyond your password. At sign-in you also enter a rotating code from a mobile authenticator app such as Google Authenticator or 1Password.

<Steps>
  <Step title="Open 2FA settings">
    Find **Two-factor authentication** in the right-hand card and click **Enable**.
  </Step>

  <Step title="Scan the QR code">
    Use an authenticator app to scan the QR code shown on the page, or enter the key manually.
  </Step>

  <Step title="Enter the code to confirm">
    Enter the six-digit code from your authenticator and click **Confirm** to finish binding.
  </Step>

  <Step title="Save recovery codes">
    The system shows a set of recovery codes one time. Save them somewhere safe. If you lose your authenticator, you can use a recovery code to sign in and disable 2FA.
  </Step>
</Steps>

<Warning>
  Recovery codes are only shown once. After you close the page, you cannot view them again. Save them to a password manager or an offline secure location.
</Warning>

## Register a Passkey for passwordless sign-in

Passkeys let you sign in with fingerprint, face, or your device PIN. They are more secure and faster than passwords.

<Steps>
  <Step title="Open Passkey settings">
    Find the **Passkey sign-in** section in the right-hand card and click **Bind Passkey**.
  </Step>

  <Step title="Complete registration on your device">
    Follow the browser prompt to register using your device's fingerprint, face, or security key (for example a YubiKey).
  </Step>

  <Step title="Sign in with a Passkey">
    Next time, choose **Sign in with Passkey** on the sign-in page.
  </Step>
</Steps>

<h2 id="bind-a-third-party-account">
  Bind a third-party account
</h2>

If you already have a password-based account, you can link one or more third-party accounts (GitHub, Discord, and others) and use either sign-in method afterwards.

<Steps>
  <Step title="Open the binding UI">
    In the **Settings** section of your profile, find the provider you want to bind.
  </Step>

  <Step title="Complete OAuth authorization">
    Click **Bind** to jump to the provider's authorization page. Approve the request and you are redirected back with the binding complete.
  </Step>
</Steps>

<Note>
  You can unbind third-party accounts at any time. To avoid losing sign-in access, keep at least one working sign-in method (a password and ideally at least one bound third-party account).
</Note>
