I was trying to update my password on the AMEX site. I logged in via 1Password and went to the "change password" section where I used 1Password to enter my old password in the first field, generated a password, and clicked "fill" to fill in the two remaining fields. I then went to 1Password and pasted in the new password there, then clicked "submit." Unfortunately, 1Password had given me a 9-character password, and the site only accepts 6-8 character sites -- so all three files were zeroed out, including the "old password" which I'd just overwritten. I remember that 1Password used to have a password history section -- but I can no longer find it, and there's nothing in the login item itself. Consequently I can't get into the AMEX site at all.
Restoring a previous data file isn't an option, because I've made a lot of other changes tonight. How can I find where the previous value of the password for this account is located?
