Need to impose rules on the user-name and need for imposing stricter rules for validating email

[sindhuja184]

Currently, the input fields of user name and the e-mail are taking any kind of arbitrary values.

Implications of Arbitrary Values
Invalid Emails: Users can enter malformed email addresses. This would lead to errors during the sign-up or login process.
Empty or Invalid Usernames: If you don't check for valid usernames, users may input empty strings, special characters, or excessively long strings, leading to potential issues.

I would like to work on this issue., please assign it to me.
