Updating passwords is slow and laborious. Ideally, i would like to change mine every 12 months, but updating 700 sites required a bit of effort and time.
Agile Bits should push for a 'change password' standard that all websites and frameworks could implement, which would allow password apps to change the password from within the app, just sending a JSON or XML command/packet over SSL/HTTPS with details like:
which could go to domain.com/api/user/update-password
If the top password apps got together to build the standard, and then started to ask frameworks, apps, and large websites to support it, i think a change could start to happen.
