When customizing the following screen in Universal Login:

Prompt: reset-password

Screen: reset-password-email

A button exists called "Resend email" as per the below screenshot:

The "Resend email" button does not inherit the primary button properties configured in the theme.

• Universal Login Customisations

Universal Login treats the primary buttons as Call to Action (CTA) buttons; in other words, users must click them to progress through the flow. The CTA buttons are considered the primary buttons and inherit the primary styles configured in the theme.

The reset-password-email screen, however, the Call to Action is for the user to check their mailbox rather than clicking a button. The Resend email button, therefore, inherits the secondary properties from the theme, as the design intention is to draw the user's attention to the text on screen rather than the Resend email button.

There is currently no way to amend the colour of the secondary button (the borders and labels can be configured) in a no-code fashion. Customers expressing an interest in configuring a button colour for the secondary properties are encouraged to log product feedback detailing their use case and requirements for Auth0 product teams to review and add to the roadmap going forward.
