I was playing around with my newly ring that I just got and decided to set a password on the tags. I've set identical (as I thought) passwords on the two tags. Later when I tried removing the password it only worked for one of the them. My guess is that I've somehow mistyped the password... Question is, is it possible to remove password from the tag?

P.S. Ring: Eclipse. App used: NFC Tools. Phone: Nexus 5.
