This article explains why it is not possible to customize the message displayed on the following screens when a user fails to enter the One Time Password (OTP) during Multifactor Authentication (MFA) login when the Enable WCAG 2.2 AA compliant UI for Universal Login option is toggled on. The default message displayed is Please enter a code.

• Prompt: mfa-sms
• Screen: mfa-sms-challenge

• Prompt: mfa-voice
• Screen: mfa-voice-challenge

• Prompt: mfa-email
• Screen: mfa-email-challenge

• Prompt: email-otp-challenge
• Screen: email-otp-challenge

See the following screenshots of the error message with Enable WCAG 2.2 AA compliant UI for Universal Login toggled off and on:

• Enable WCAG 2.2 AA compliant UI for Universal Login: OFF

• Enable WCAG 2.2 AA compliant UI for Universal Login: ON

• Custom Text

The correct key is no-code, but it does not save correctly to the backend. 

The Auth0 engineering team is aware of this issue and has added it to the backlog. There is currently no ETA for a resolution.
