Hi, what is Auth0’s recommendation for integration into a browser extension? We are running into roadblocks related to cross-origin and third-party cookie restrictions, etc and also not finding much guidance on the Internet unfortunately. Please advise. Thx

Also–the deprecation notice should indicate why it was deprecated (no one willing to maintain, insecure, etc.) Edit: I noticed auth0-chrome just stores the refresh token in local storage. Is that considered safe? Edit 2: Would Auth0 recommend chrome extensions use the implicit flow?

Hi @trackers153,

As you have likely seen in the thread you posted and [other threads](https://community.auth0.com/t/auth0-chrome-alternative-for-login-from-chrome-extension/54256) in the Community, we don’t have much official guidance on browser extensions.

We would appreciate your input about the use-case and your feedback. You can do the here: [Auth0: Secure access for everyone. But not just anyone.](https://auth0.com/feedback)
