User reviews

Users appreciate Keeper Password Manager's strong security, responsive support, and convenient cross-device use with a clear interface. However, multiple reviews report significant performance issues including browser slowdowns, high memory consumption, and software bugs causing Firefox to hang or freeze. Additionally, recent versions fail to stay logged in after closing Firefox, impacting usability. Some users experience auto-fill problems and express concerns about confusing subscription auto-renewals. Despite drawbacks, many consider it more trustworthy than alternatives.

  • Difficulty managing subscription such as auto-renewal without clear notifications.
Recent reviews
Strong password protection. Not easiest to use, however, it is very useful and protective.

This extension is lagging and slowing down firefox so much, that I genuinely have to disable it when I don't need to use it because googling something or opening a new page adds an extra one or two seconds of loading in order for the website to load instead of them loading in under a second. It is infuriating. Even with all of the prompts and recognition of password fields disabled, the extension still lags webpages an extreme amount.

Extension safety

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.

Keeper® Password Manager & Digital Vault requires a lot of sensitive permissions. Exercise caution before installing.

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 Browser Add-ons, 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.

Keeper® Password Manager & Digital Vault is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
