I am novice Ubuntu user. For laughs I encrypted an external USB drive and put a punch of secret stuff on it. It used to be that every-time I would attach the drive I would be challenged for a password. At some point I inadvertently clicked "remember password" and now the volume mounts automagically.

How can I remove the cached password so I will be asked for a password each time I mount the volume?

How did you encrypt the flash drive? What tool/application? – gertvdijk Jan 10 '13 at 23:15
I used the Disk Utility. Removed the exFat partition that it came with and created a new EXT partition and I think I just checked the option for "encrypt volume". – dotdawtdaught Jan 10 '13 at 23:33

Launch Password and Encryption Keys from the Unity dash. Try to find the stored password matching your USB drive, right click and delete it.

Thanks man, that did the trick! I see a bunch of cached passwords for SMB shares that I removed too :P – dotdawtdaught Jan 10 '13 at 23:35
