try clicking keychain and see if it wants you to put your pw in again

If not, try fully closing browser and then try again

If all that fails, I’m not sure

Just general troubleshooting ideas from me, I haven’t logged in in a bit lol

This normally happens when a new session started after closing the browser.
It will work if you double click the keychain extension if it's part of the browser you are using as mentioned by Khal.
