User Reviews

Overall, reviews are positive. Users praise Proton Pass for being easy to use and quick to set up, with strong privacy and security that keeps data safe. Many users say it’s reliable and does what it promises, and appreciate features like a secure vault for passwords and passkeys. The main recurring drawback is autofill reliability—credentials are not always filled correctly, and prompts can disappear too quickly. A few reviewers suggest UI improvements or minor feature tweaks, but the consensus remains favorable and confident in its value.
Pros

  • Strong privacy and security; trusted with data
  • Reliable performance; generally no issues and does what it promises

Is Proton Pass Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Proton Pass requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
  • High ****** *** ********* ** ******* *** ******* ******* ** ****** *** *** ******** ******

  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
  • Low ******* ****** ** *** ********* ******** *********
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Proton Pass has earned a fairly good reputation and likely can be trusted.
