I installed avast on a secondary PC on my network. I went with avast mostly because of the password sync feature.
I installed Passwords on this device too, but I cannot get the passwords section in main settings windows (gear).
Also, this device is not shown on my primary device below the sync password options. I can only see the primary device itself and my phone. BUT I can see it in my avast account (web or main interface,…)
I did a clean install of Avast, but it didn’t work.
Then I saw at the bottom of the password section (main interface) that there was like a wizard to go through to install browser addon and import passwords.
After I did that, Passwords showed up in the settings.
So to sum up (I,m not 100% sure about that) I think you have to install browser extension so the settings can be reached. I don’t think this is a good idea though because there are some people like me who do not really want any extension or autofill, and simply want a password manager (I suppose)
