Very easy to use, seems very secure, plenty of options, trusted company.

Amazing password manager, highly recommend.

It is easy and convenient to use, and it also works perfectly with other addons such as Multi-Accounts Containers

Overall I really like this extension. Most of the time works flawlessly, greatly assists me in keeping my accounts secure and I like how the Proton ecosystem syncs over my devices. Only small gripe is that the extension will often ask me if I want to save a username and password for a site when it already has the details for that site... not sure on the cause but only a very small annoyance. Highly recommend this, and the other Proton products.
