Bitwarden auto fill password#
With this revamp, Bitwarden is about on par with other password manager services that warn users before they fill in iframe login forms. That means subdomains for trusted domains still get a pass.
(If they fail to protect users against this kind of exploit, everyone’s in far bigger trouble.)īitwarden’s documentation will help walk you through adjusting your whole password vault or per-entry matching rules.īitwarden is, however, keeping the same default matching rules as before this update-any URL that matches a base domain (e.g., and ) saved to your password vault or on Bitwarden’s default match list will be considered trusted.
For example, Apple should have the resources to guard against compromised HTML elements.
Bitwarden auto fill free#
If you decide to stick with Bitwarden, which is an otherwise reliable service and our favorite free password manager, you should also leave off preemptive autofill. Use a service or app that won’t autofill forms hosted on external sites, or at the very least, will warn you that you’re about to do so.Good services and apps have this disabled by default-leave it that way for better security. (And no, the answer isn’t to never use a password manager.) During Flashpoint’s spot check of rivals, they only autofilled for the site saved in the vault entry, or at least flashed a warning if an iframe pulled in an external form.Īs a password manager user, you can take two major steps to protect yourself from this kind of vulnerability. Meanwhile, other password managers look like safer options, as they remain stricter with their autofill policies. Bitwarden also doesn’t warn users when they’re filling out a form hosted on a different page or site, and gives a free pass to subdomains of a website, too. This vulnerability exists whether you have Bitwarden preemptively fill out login forms or you manually trigger autofill Flashpoint’s testing showed that either usage of autofill carries the same risk. ICloud’s login page uses iframes to enable login through -and Bitwarden cites this as one reason for its lax policy on autofill. The company gives the example of iCloud as a major website that still uses iframes to connect to for login. This permissiveness isn’t by accident, but design: In the company’s documentation about the issue, which was published in late 2018, Bitwarden states that its goal is to encourage better adaption to a password manager. If any of those external HTML elements become compromised (like advertising, a known vector for exploits), the result could be stolen login data. On websites that use iframes-where a page loads HTML elements from a different webpage-login forms hosted on an external website are still filled in with the saved site’s user ID and password info.
Bitwarden auto fill update#
However, until that update goes live, our original report and advice stand.īut as security firm Flashpoint.io detailed in a blog post last week, Bitwarden’s autofill has a deeper vulnerability than other services. Update, 3/17/23: Bitwarden says it will be releasing changes next week to its autofill behavior, which we’ve outlined at the end of this article along with revised recommendations for steps you can take to keep your passwords safe online. Update, 3/31/23: Bitwarden says its new warning system for autofill has gone live.
