When logging into Magento (v2.1.2), I am able to successfully login using my password, and then I am immediately redirected to an account page that states 'It's time to change your password'.
Upon updating the password, Magento will not accept any value I enter into it, always displaying the error message
Sorry, but this password has already been used. Please create another.
I know there's no possible way all the combinations I've tried using have previously been used, even making up completely new passwords to try.
I've also manually updated the admin users password through the mysql database, and upon logging in get thrown into the same loop.
Has anybody else dealt with this issue, or have any suggestions?
