Jan 2021 Update: Switched to Bitwarden. Works like a charm.

Original review: Was (and still is) working great for my 5 existing PCs, but when I try to install it on any new PCs or VMs, I am unable to connect to and use pCloud.
Error = "Invalid Client ID".
Plus the Add-On now appears to be abandoned. Too bad. It was awesome.

I like the idea, but it asks for the master password very often (at least with google drive), even when the slider is moved to "remember for 24 hours", so fast logins without writing a password are not possible. While this issue exists I prefer using other solutions based on local db files

I would give it 5 stars if i didnt have to authorize google drive every single time, very annoying.
EDIT: I finally figured out what the issue was,I believe it was user error. I went into the settings, I didnt know it was there, and added it there, now it works everytime. updated to 5 stars, since it is excellent add on .
EDIT:Nevermind,came back up today. this is annoying, removing this add on until this is fixed.

Must say, i tried really hard to make it works but still 401 error for no reason, also putting on cloud technology your datafile sounds a bit unwise.
Have potential to be great but UI needs big improvements to reach a larger public
