Proton apps are very reliable in general. This password manager is the one I use the most, along with the VPN.

Although the premium version offers a lot of tools, the free tier already gives us the most productive tools for our day-to-day activity.

The most useful features are the password generator and autofill. You will be able to use extremely safe and complex passwords that you won't need to remember.

If you absolutely must remember a password, there is an option to create more memorable, although still safe passwords, such as "Amid6-Although1-Condense8-Slip1", for example.

Being an open source application based in Switzerland, it offers both technical and legal layers of protection.

If you are looking for a reliable password manager, this is one of the best alternatives.
