Online documentation for Password Slug.

These days people can have hundreds of online accounts, out of which only a handful have personal information that they want to protect with a slug. Hence, Password Slug is designed to stay out of your way and only trigger on login forms that are important to you. This is where you define these login forms using a combination of username and site (domain or URL). When a login form has a matching username and site, the slug will be added to the password that is autofilled by your password manager. Some things to note:

  • One entry per line.
  • The username is optional. If no username is entered, the slug will be added for all users on that site.
  • If a username restriction is used, separate the username and site with a space.
  • The username is an exact match while site is a partial match against the URL. Both matches are case-sensitive, though you can force a case-insensitive match using regular expressions (see below).
  • If either username or site is surrounded by forward slashes, then it will be treated as a regular expression, a powerful text matching syntax. For example, /gmail|yahoo/ would match any URL containing “gmail” or “yahoo”; and /sam/i would match the username “sam”, “Sam”, or “SAM” on the site. You can test your regular expressions at

Settings tab

This is where you configure the slug that will be added to the password after it is autofilled by your password manager. Here is a description of each field:

  • Slug – the text to be added by Password Slug.
  • Sound effects – toggle for the lock sound that plays when a slug is added. Even if this is disabled, you can still tell when the slug is added by the padlock (🔒) that appears on the Password Slug extension icon in the toolbar.
  • Position – the location in which to add the slug. It can be prepended before the password, appended after the password, or inserted in between each character of the password. Don’t forget to update the password in your accounts with the slug in the same position.
  • Preview – this shows you a preview of where the slug would be added.

Frequently asked questions.

How do I know Password Slug isn’t stealing my passwords? First of all, Password Slug is an MV3 extension, which means it’s inherently safer since MV3 extensions can’t load or execute remotely hosted code. Also, browser extensions do not have compiled code like desktop applications—they are written in plain text using HTML, CSS, and JavaScript, so you can inspect the source code for yourself. In fact, we encourage you to do this to put your mind at ease before you start using Password Slug. Here’s how:
  1. Go to where extensions are installed and open the ccldjkcolceiikfhipiplcakimnnaeaj folder. This is where you’ll find the source code for Password Slug.
  2. Go into all the subfolders and inspect all files. Search for the two ways in which Password Slug could communicate with remote servers: XMLHttpRequest and Fetch API.
You should see that there’s one Fetch call to an .md file, which is a plain text file in Markdown format used to publish our news updates. Apart from that, Password Slug doesn’t have any other interactions with remote servers.
I just installed Password Slug, but where the heck is it? After installing Password Slug, it should show up in the Extensions menu (jigsaw puzzle icon) on the Chrome toolbar. If you want Password Slug to always be accessible directly from the toolbar, then click on the thumbtack icon to “pin” it so that the Password Slug extension icon will always be visible.
How do I use Password Slug with LastPass? Setting up Password Slug to work alongside LastPass is as simple as one-two-three:
  1. For each account that you want to protect with Password Slug, enter the website’s domain or URL into the Accounts box (one per line). You can optionally restrict them by username as well.
  2. Go to the Settings tab and enter the additional text (i.e., the “slug”) that will be added to your passwords into the Slug field. By default the slug is appended at the end of the password, but you can change the position to a combination of before, after, and in between.
  3. Log in to the accounts that you listed in step 1 and update the passwords so that they include the slug that you defined in step 2. Note that the passwords stored in LastPass can be left untouched as the slug will be autofilled by Password Slug immediately after LastPass runs.
If you want us to walk you through this, then watch our video tutorial to see Password Slug in action. Keep in mind that the setup process outlined above and seen in the video can be applied to other password managers as well, which means you can use Password Slug with just about any password manager browser extension. Please let us know if your password manager isn’t playing well with Password Slug.
Does Password Slug track me or collect clickstream data in any way? No, Password Slug doesn’t implement any sort of tracking or clickstream collection. We will never collect clickstream data, but in the future we reserve the right to track anonymous usage data (e.g., which option is clicked on the most) in order to improve our product. We value privacy ourselves, so we respect other people’s privacy. Please read our Privacy Policy for more information.
What if I factory reset my computer, are part of my passwords gone forever? No, the other part of the password (the “slug”) is something that YOU define, so you can never lose it unless you forget what the slug is. Remember that you would add the same slug to all of your passwords, so there will always be only one text string to remember. Even if you don’t have Password Slug installed, you can manually enter the slug yourself after the password manager autofills the incomplete password. Password Slug is there to autofill the slug for you so you wouldn’t have to type it in manually. It’s worth mentioning that the Password Slug settings are synced to your Chrome profile, so as soon as you log in to Chrome on a new computer and install Password Slug, your settings will be restored.
How did you build Password Slug? Password Slug was created with love using Svelte, Vite, TypeScript, daisyUI (a Tailwind CSS plugin), and Showdown.
Will there be versions for Firefox and Edge browsers? We plan to release a version of Password Slug for Microsoft Edge soon. Regarding Mozilla Firefox, that is still an unknown. The reason is because MV3 extensions for Chrome require what is called a service worker, which currently isn’t supported in Firefox extensions. Mozilla’s latest update is “we plan to support service workers in the future for compatibility,” but no official date is given. As soon as Firefox MV3 extensions support service workers, we will release a Password Slug version for Firefox.
