Bittensor Wallet Extension - No Password/PIN Authentication Security Issue

[Shoeman8]

Issue Summary

The Bittensor wallet extension (v2.0.2) does not require password/PIN authentication when opened, creating a security vulnerability for users with significant TAO holdings.

Environment

• Browser: Chrome
• Extension Version: 2.0.2
• Network: Finney (mainnet)
• Operating System: Windows

Current Behavior

• Wallet opens immediately without any authentication
• No password/PIN prompt even in incognito mode
• No visible security settings in the wallet interface
• Extension remains unlocked indefinitely

Expected Behavior

• Wallet should require password/PIN authentication on startup
• Should have security settings to enable/configure authentication
• Should auto-lock after a period of inactivity
• Should require authentication after browser restart

Security Concern

I have 25+ TAO in my wallet (significant holdings), and the lack of authentication poses a serious security risk if someone gains access to my computer.

Steps to Reproduce

1. Install Bittensor wallet extension v2.0.2
2. Set up wallet with seed phrase
3. Close browser completely
4. Reopen browser and click wallet extension
5. Wallet opens immediately without authentication

Additional Information

• Unable to find any lock/security options in wallet settings
• Checked all menu options and settings pages
• Issue persists across different browser sessions

Request

Please add password/PIN authentication feature or provide guidance on how to enable existing security features if they exist.
