Mozilla Account Manager
For some time now, I've been happily using 1Password to manage all of my online accounts. I really like it and recommend it to all of my friends, but I do have a few reservations:
- It uses a proprietary format for storing my account information. (Older versions used the Keychain format.)
- It does not integrate with Mobile Safari or anything that's not a browser (e.g., iTunes). This means browsing on my iPhone or iPad is practically impossible, and my iTunes password has to be easy to type, leaving me vulnerable.
- There's currently no way for developers to make sure their sites support 1Password. Given the way 1Password works, microformats seem like a possible solution.
Earlier this year, I heard about Account Manager, a new effort from Mozilla that aims to help web sites and users connect in a safe and consistent way. In other words, it can potentially make managing passwords online a lot easier, more consistent, and more secure. Furthermore, because it's being developed as an open standard, widespread support is a possibility.
The spec uses MediaWiki, which does not number sections by default. Because all references within the spec use section numbers, you might want to log in and select "auto-number headings" in your preferences. (You can also refer to the table of contents at the top.)
This weekend, I managed to find some time to explore Account Manager a bit. With the help of Dan Mills, I got it working with Firefox 4. He was also kind enough to provide some preview builds for you to use:
- firefox-4.0b4pre.en-US.mac.dmg (Mac)
- firefox-4.0b4pre.en-US.linux-i686.tar.bz2 (Linux)
- firefox-4.0b4pre.en-US.win32.installer.exe (Windows)
If you want to try it out before I give you a quick tour, install one of the Firefox 4 preview builds linked above, and visit my Account Manager demo.
Implementing Account Manager is pretty straightforward. To keep things simple, I'm only going to show you how to implement login and logout. Think of this as two steps:
- Inform the browser whether the user is logged in.
- Inform the browser how to log in and log out.
The first step is accomplished via the X-Account-Management-Status header. (This is a response header you can set with the header() function.) Here's an example:X-Account-Management-Status: active; id="chris"; name="Chris Shiflett"; authmethod="username-password-form"
This header informs the browser that the user is currently logged in as chris. Instead of active (logged in), you may specify none (not logged in) or passive (remember me). The rest of the header is a semicolon-delimited list of attributes, three of which are currently defined: name, id, and authmethod. There are various options for authmethod, but I'm only going to be talking about username-password-form.
Informing the browser how to log in and log out is almost as easy. You indicate these things in an Account Management Control Document (AMCD). You can view my AMCD to get an idea of the format, but because json_encode() doesn't generate the most readable JSON, I'll share the PHP as well:A
