Enhancement: Add minimum password strength validation to Signup form

[pericharlabindhumadhavi-data]

What's the problem?
The signup form only has required on the password field no minimum length, no complexity rules. A user can sign up with a single character as their password.

For a medical diagnostic portal handling patient data, this is a real concern. Basic password strength is an expected minimum.

Where is it happening
src/app/auth/signup/page.tsx — password field

What I'm suggesting
Add client-side validation to enforce:

• Minimum 8 characters
• At least one number
• Show a clear inline error message when the rule is violated

Why it matters
This is a clinical tool used by doctors with access to patient diagnostic records. Weak passwords on such a portal are a genuine security concern.

I would like to work on this issue under GSSoC.
Thank you.

Hello @Pushkarini579 ,

I would like to work on this issue under GSSoC.

After reviewing the codebase, I found that the password field in src/app/auth/signup/page.tsx currently only uses the required attribute, allowing users to register with extremely weak passwords. Given that this application handles medical and patient-related data, implementing basic password strength validation is important for improving account security.

My implementation will include:

• Enforcing a minimum password length of 8 characters.
• Requiring at least one numeric digit in the password.
• Displaying clear inline validation messages when the requirements are not met.
• Preventing form submission until the password satisfies all validation rules.
• Ensuring the changes integrate smoothly with the existing signup flow and UI.

This enhancement will help improve the security of user accounts and align the application with basic authentication best practices.

Please assign this issue to me.

Thank you!
