Tunnelbear asking for access to iCloud keychain

It is not recommended to contribute your keychain access to any product.

This is because you cannot know whether they just want to provide the 2FA product or h access to your bank card information from your existing password bank.

Sounds like a VPN. Are you using Tunnelbear VPN?

Before allowing it access to your keychain, check their support area first.
