Remove "Try Another Method" Link when Only One MFA Factor Is Enabled

When a user is prompted for Multi-Factor Authentication (MFA), the "Try another method" link appears at the bottom of the Universal Login widget. This occurs even though the user is enrolled in only a single MFA factor, specifically the Phone factor.

• Auth0 Universal Login
• Multi-Factor Authentication (MFA)
• Phone Factor (SMS/Voice)

This behavior occurs because the Phone factor is technically capable of two distinct delivery methods: SMS and Voice. If the tenant configuration for the Phone factor allows both SMS and Voice, Auth0 treats these as two separate methods. Consequently, the Universal Login widget displays the "Try another method" link to allow the user to switch between receiving a text message (SMS) and a phone call (Voice).

To remove the link, ensure that the enrolled factor only has a single delivery method available. The safest and most reliable way to remove the "Try another method" link is to restrict the Phone factor to use a single delivery channel.

1. Log in to the Auth0 Dashboard.
2. Choose Security > Multi-factor Auth.
3. Select the Phone factor.
4. Locate the Delivery Method section.
5. Select SMS or Voice.
6. Click Save.

Once saved, because only one delivery method exists, the widget no longer renders the option to switch methods.
