I had to post this here.
I just did a password reset for my Tumblr account and I don’t understand the logic there for 8 character password.
The password I was trying to reset to was 9 characters and the error message I kept on getting was “Password should be at least 8 characters” . I dropped the last character and it worked.
Tumblr, first fix your error message to say “Password should be 8 characters only” and if you think like me and see the sense in letting users decide to have more than 8 characters then save them the pain of having to remember 8 character password they had to come up with.
It may save your users to repeat the experience.
