🐛 Bug Report: Username validation allows only letters and rejects valid usernames

[harendra-godara]

📜 Description

Description

The username validation currently allows only alphabetic characters, which rejects many valid GitHub-style usernames containing numbers or hyphens.

For example:

• harendra07
• john-doe
• dev123

are rejected even though they are valid and commonly used usernames.

Steps to Reproduce

1. Open the Signup/Login page

2. Enter a username containing:

   • numbers (user123)
   • hyphens (john-doe)

3. Submit the form

Expected Behavior

The username field should accept valid GitHub-style usernames containing:

• letters
• numbers
• hyphens (-)

Actual Behavior

The validation only allows letters and rejects otherwise valid usernames.

Impact

This creates a poor user experience because many real-world usernames are incorrectly treated as invalid.

Suggested Fix

Update the username validation regex to support commonly accepted username patterns similar to GitHub usernames.

Hi @harendra-godara , I’d like to work on this issue under GSSoC’26.

• I identified that the current username validation regex only allows alphabetic characters, causing valid usernames like user123 and john-doe to be rejected.
• I plan to update the validation pattern to support GitHub-style usernames containing letters, numbers, and hyphens while still preventing invalid formats.
• I’ll ensure edge cases such as consecutive hyphens, leading/trailing hyphens, and empty usernames are handled correctly if required by the project rules.
• I’ll also add/update validation tests to cover both accepted and rejected username patterns.
• This will improve usability and align the username validation behavior with commonly used real-world username standards.
