1Password for Safari: excessive CPU usage
From time to time the 1Password web extension in Safari drains my MacBook Pro's battery; according to the activity monitor it's then occupying 100% CPU (only one core? don't know). Unfortunately I cannot really tell exactly *when* this happens, but I *think* it's when my Mac goes to sleep, for example when I'm away or close the lid, Safari is still running, and I come back later.
Side effect:
When unlocking 1Password via the menu bar icon, the extension in Firefox is directly unlocked too, but the Safari extension keeps being locked; I manually have to click on the button to unlock it.
This keeps bugging me now for quite some time, and the only workaround I found so far is either deactivate and reactivate the extension in Safari settings or restart Safari.
Deinstalling and reinstalling the application didn't help as far as I could tell.
Has someone else seen this?
I'm using
* 1Password for Mac 8.12.10 (81210036)
* 1Password for Safari 8.12.10.36
* macOS 26.4.1
* MacBook Pro M2

Could you reproduce the behaviour, and then create some diagnostics reports from both the extension and desktop app:

Hi Thorsten, thank you for opening this discussion. I am also having the same issue. How was this solved? I see the case is marked as solved but there is no explanation on why this is happening and how to fix it.
