Browsing the web with a password manager can help make it seamless. You simply autofill your logins and passwords when needed. Sometimes websites handle logins in such a way that autofill might not work and you just copy and paste your credentials. Now, with Bitwarden **fill assist**, a single report can deliver rapid improvements to autofill for all users.

## Introducing Bitwarden fill assist in all browser extensions

Now available as an opt-in setting, **fill assist** ensures seamless autofill for websites that users report to Bitwarden as needing special autofill rules. With this setting on, the Bitwarden extension will check for any tailored rules to ensure accurate autofill.

This advanced function brings an added dimension and capability to Bitwarden autofill, with a resounding impact to making logins fast and easy for everyone. In short, when users report websites to Bitwarden as having unique autofill requirements, it is rectified and offered to millions of Bitwarden users much more rapidly.

## How it works

**Fill assist** references a database of tailored autofill rules curated and maintained by Bitwarden. Any website reported to have issues will be analyzed, reviewed for impact, and a Bitwarden engineer authors specific autofill instructions published for **fill assist** to autofill seamlessly.

When you turn **fill assist** on from the **Settings > Autofill** **> Additional options** menu, your browser extension will periodically sync this rules database. When you are visiting a site that matches a URL within it, the extension will switch from using the default autofill logic to following those customized instructions for the site.

> In the sequence above, TikTok.com's login is coded as though it were a new password field, as evidenced by Bitwarden asking to generate a new password instead of using a saved one. **Fill assist** is then turned on, and after a vault sync to cache the rules database (only required once and not shown in the recording), Bitwarden is able to properly autofill the password with the one saved in the vault.

The database is [currently hosted on GitHub](https://github.com/bitwarden/map-the-web/) and only Bitwarden engineers are capable of adding entries. Your extension’s copy of the database is stored locally and your extension sends no data to Bitwarden or GitHub on usage.

Perhaps the greatest strength of this process is that there’s no dependency on a new extension version: database additions can improve autofill for everyone the same day the new rules are written.

## A call to the community

Your single report can impact millions of Bitwarden users, improving their web browsing experience. Thank you in advance for taking the time to submit the reports and making autofill better for everyone!

## Plans for the future

**Fill assist** is now in its first phase of several planned. In this phase, the feature is opt-in, and the centralized database is hosted on GitHub. Soon there will be enterprise policies for fill assist settings and the capability to have an organization-owned database alongside the Bitwarden-curated one for private websites like intranet pages. Further out, **fill assist** will be on by default for all users with an option to opt out. In the future, users will be able to opt into other community-sourced or personal rules databases.

This is just the beginning of an improved autofill experience for everyone. You can help now by reporting websites today that need autofill assistance!
