Can you please help me?
Thank you, Michal.

Hello Michal,
Could you tell me more about your environment :
- Browser type and version ?
- Passbolt version ?
Can you provide us with the browser debug console. To open the browser debug console, please follow the following doc :
Firefox: [https://developer.mozilla.org/en-US/docs/Tools/Browser\_Console](https://developer.mozilla.org/en-US/docs/Tools/Browser_Console)
Chrome: [https://stackoverflow.com/a/10258029/4063145](https://stackoverflow.com/a/10258029/4063145) (The background page here is index.html)
Note: We are currently deploying a new version of the plugin, it could be related. Can you try to restart your browser and try again if it is not done yet.
Best regards,
Cedric

Thank you for your feedback @tobi and @grave
I can reproduce it with a v2.1.0. The backward compatibility has been broken with API \< v2.2.0.
We are working on a fix and we’ll keep you posted.
Note that the versions of the API you are using are almost one year old. We do encourage you to update your passbolt. You can find more information here: [https://help.passbolt.com/hosting/update](https://help.passbolt.com/hosting/update).

A new version (v2.9.2) of the browser extension has been released and fix this backward compatibility issue with API \< v2.2.0. Google and Mozilla are currently rolling out the new version and it can take time. You can manually force the update of the plugin if your need to access quickly your passwords.

@grave [FAIL] The public key cannot be used to verify a signature.
This is known to us and this warning should not be.
I just created [a ticket on github](https://github.com/passbolt/passbolt_api/issues/317) to tackle and follow-up on this issue.
