|
|

|
|
|
|
You can reconfigure your two-factor authentication (2FA) settings or add new 2FA methods without disabling 2FA entirely, allowing you to keep both your recovery codes and your membership in organizations that require 2FA.
|
|
|
|
## Changing an existing two-factor authentication method
|
|
|
|
{% ifversion fpt or ghec %}
|
|
You can configure a different authenticator app or change your phone number, without disabling 2FA or creating a new set of recovery codes.
|
|
|
|
### Changing the TOTP app
|
|
|
|
{% endif %}
|
|
|
|
You can change the time-based one-time password (TOTP) application you use to generate authentication codes.
|
|
|
|
{% data reusables.user-settings.access_settings %}
|
|
{% data reusables.user-settings.security %}
|
|
{% data reusables.two_fa.edit-existing-method %}
|
|
{% data reusables.two_fa.enable-totp-app-method %}
|
|
{% data reusables.two_fa.save-2fa-method-when-editing %}
|
|
|
|
> [!WARNING]
|
|
> Changes to an existing 2FA method will only take effect after you have provided a valid code from the new method and clicked **Save**. Only replace the existing 2FA method on your device (e.g. the {% data variables.product.prodname_dotcom %} entry in your TOTP app) after your new method is saved to your {% data variables.product.prodname_dotcom %} account completely.
|
|
|
|
{% data reusables.two_fa.manual-totp-app-setup %}
|
|
|
|
{% ifversion fpt or ghec %}
|
|
|
|
### Changing the SMS number
|
|
|
|
You can change the phone number you use to receive authentication codes via SMS.
|
|
|
|
{% data reusables.user-settings.access_settings %}
|
|
{% data reusables.user-settings.security %}
|
|
{% data reusables.two_fa.edit-existing-method %}
|
|
{% data reusables.two_fa.enable-sms-number-method %}
|
|
{% data reusables.two_fa.save-2fa-method-when-editing %}
|
|
|
|
{% endif %}
|
|
|
|
## Adding additional two-factor authentication methods
|
|
|
|
We recommend adding more than one 2FA method to your account. This ensures that you can still sign in to your account, even if you lose one of your methods.
|
|
|
|
In addition to adding multiple 2FA methods, we strongly recommend setting up multiple recovery methods to avoid losing access to your account. For more information, see [AUTOTITLE](/authentication/securing-your-account-with-two-factor-authentication-2fa/configuring-two-factor-authentication-recovery-methods).
|
|
|
|
{% ifversion fpt or ghec %}
|
|
|
|
### Adding a TOTP app
|
|
|
|
You can add a time-based one-time password (TOTP) application to generate authentication codes.
|
|
{% endif %}
|
|
|
|
{% data reusables.user-settings.access_settings %}
|
|
{% data reusables.user-settings.security %}
|
|
{% data reusables.two_fa.add-additional-method %}
|
|
{% data reusables.two_fa.enable-totp-app-method %}
|
|
{% data reusables.two_fa.save-2fa-method-when-editing %}
|
|
{% data reusables.two_fa.manual-totp-app-setup %}
|
|
|
|
{% ifversion fpt or ghec %}
|
|
|
|
### Adding an SMS number
|
|
|
|
{% data reusables.two_fa.sms-warning %}
|
|
|
|
{% data reusables.user-settings.access_settings %}
|
|
{% data reusables.user-settings.security %}
|
|
{% data reusables.two_fa.add-additional-method %}
|
|
{% data reusables.two_fa.enable-sms-number-method %}
|
|
{% data reusables.two_fa.save-2fa-method-when-editing %}
|
|
|
|
{% endif %}
|
|
|
|
## Setting a preferred two-factor authentication method
|
|
|
|
If you have multiple 2FA methods, you can choose a preferred method that will be shown first when you are asked to authenticate with 2FA.
|
|
|
|
{% data reusables.user-settings.access_settings %}
|
|
{% data reusables.user-settings.security %}
|
|
1. Under "Two-factor authentication" in "Preferred 2FA method", select your preferred 2FA method from the dropdown.
