User Reviews

User reviews are mixed. Many praise reliability and smooth 2FA across devices, with some UX improvements in recent updates. However, pervasive, intrusive prompts, poor configurability, performance slowdowns, and compatibility problems (e.g., Prism.js, Samsung login, console errors) are frequent complaints. The UI is clunky and can hijack forms, and onboarding can feel overcomplicated due to mandatory Secret Key usage and corporate enforcement. Some reviewers long for mobile support. Overall, usability and performance issues often outweigh security/reliability benefits.
Pros
  • Reliable across years with smooth 2FA integration
  • Easy to use across devices and platforms
  • Recent updates improve UX (fewer toolbar clicks)
  • Security model includes a Secret Key for extra protection on new devices
Cons
  • Intrusive, frequent pop-ups and prompts; lack of a 'don’t ask again' option
  • Significant performance degradation and browser slowdowns
  • Site compatibility and reliability issues (breaks prism.js, login issues on Samsung, console errors)
  • Usability/UI problems (hijacking form fields, outdated UI, overlay covering Show Password)
  • Cumbersome onboarding and corporate enforcement; mandatory usage and secret key requirements

Is 1Password: Password Manager 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.

1Password: Password Manager requires a lot of sensitive permissions. Exercise caution before installing.
