Resetting your password is not an issue if you have a good reason for doing it. The warning is put in place for anyone trading with that user to take some extra precautions. This could be asking you to produce a signed signature from an address you used at some point, which will not be an issue since you're the owner of the account.

You can preempt this and make a reply in the stake your address thread about the change in password or email.

If you can remember your password, it's a poor password choice and should be changed.
Passwords should be complex with a mixture of alphabets, numerals and special characters.
