I've used Clockwork since my Droid X days and this is the first time I've seen TWRP. It looks fancy and sleek but its causing me some problems. I "made" a backup of my stock 4.4.2 and later on wanted to back up my AOKP 4.4.2 ROM. My TWRP asked me for a password, which I've never recalled setting up a password and it won't back up my AOKP, also my Stock backup disappeared as well. Any thoughts or problems like this?
