But there are plenty of sites that want you to sign up, hand over your email address, and log in whenever you want to read or download something. This can get annoying real quick, especially for sites that you plan to use only once.
Enter BugMeNot. This service at bugmenot.com uses community-generated login/password data to use sites without signing up for an account.
And now there is an Android app for it. Copy/paste the offending URL into the app, then copy/paste the login data back into your web browser to sign in without signing up.
Edit: Good news! A BugMeNot update killed the bug.
Edit: BugMeNot is now available from the share menu and takes you straight to the passwords. You still have to copy/paste 'em into the form fields yourself, but maybe that will be automated in a future update? A BugMeNot add-on for Dolphin would be great too.
For now you might as well bookmark bugmenot.com in your browser, but if the app matures a bit it may become a welcome addition to your arsenal of useful Android apps.
