Absolutely key in my day to day life, and very quick response when I was unsure how to use a feature. Couldn't recommend it (along with other Proton services such as Mail and Drive) more.

Works like a charm!

Works flawlessly. It is feature rich and easily comparable to all other password managers.

EDIT: Monospace font for password field feature was recently added. I changed my review to 5 star as the only grip I had was solved. Below statement is no longer correct. I am gonna leave it though for developer response to make sense.

But it is lacking support for displaying passwords in monospace font, thus the 4⭐ rather than 5

It could still use some auto-fill improvements but it gets the basics right and I trust the folks at Proton to get the important stuff correct.

Proton is the safety pro. Until proven otherwise, unbreakable. And this advice applies to all their services

Trusted. App and Extension.

The ease of any password manager, combined with Proton's privacy guarantees, make this a trustworthy and reliable tool.

Une merveille, merci d'exister !
