When I got this app I looked for a while on password managers. iCloud Keychain came out and I figured I would wait, but liked the stuff 1Password had to offer. I bought it one day and when it had me set up my master password, I used one I knew I never used before. It's long to most people, but I feel it could be longer and more secured. I thought about changing it, but I read that it's not a good idea so I didn't. I saw a post here on how to export my info, change my password, and then import it again (forgot where). It didn't look that hard and I might do it someday when I have time.
So that is my only regret, so maybe it will be easier to change my master password in the future?
