For some reason I'm having problems with getting a somewhat secure password stick in all different types of interfaces of Toodledo.
I'm using the regular Toodledo website and the Firefox Add-in and the results of my experiments are these:
Password: 123456
Works with Toodledo: Yes
Works with FF Add-in: Yes
Password: "123456
Works with Toodledo: No
Works with FF Add-in: No
Password: #123456
Works with Toodledo: Yes
Works with FF Add-in: No
As you probably understand this makes for something of a limit between interfaces and usage of a bit more secure passwords.
