Sign-up and login flow design: best practices

The sign-up and login flow is how people create an account and return to it. It should be fast for new users, reliable for returning users, and recover gracefully when someone forgets a password.

What a good one includes

The essentials:

  • Social sign-in alongside email where it suits your audience
  • Password requirements shown before the user types
  • A show-password toggle and support for password managers
  • Clear, specific error messages without revealing account existence
  • A simple password reset path

Design it with Fleck

Describe your product and Fleck generates the sign-up and login flow as part of a connected project, using your requirements, user flows and one shared design system, then audits it for UX issues.

How to design it

  1. Ask for the minimum

    Email and password, or a social account. Collect profile details later.

  2. Show rules upfront

    Display password requirements and validate inline.

  3. Support autofill

    Use correct input types and autocomplete attributes.

  4. Design recovery

    Make reset easy to find and confirm what happens next.

Common mistakes

  • Hidden password rules
  • Disabling paste in password fields
  • Errors that blame the user without a fix

Should sign-up and login be on the same screen?

They can share a screen with a clear switch, as long as the current mode is obvious and the primary action label changes with it.
