I didn't used Magento 18.104.22.168 CE for about 1 month. After that i logged in to admin after, opened the my account/Account information page, the title “It's time to change your password.” was showed. When i tried to open my products (or settings page), the similar page “It's time to change your password.” was showed
I changed my password and pressed “Save Account”. And nothing changed, i still see “It's time to change your password.”, all menu items leads to this page “It's time to change your password.”
1) run this script -
UPDATE admin_passwords SET expires = <<some future timestamp>> WHERE user_id = <<admin_user_id>>;
i have used
<<some future timestamp>> = 1999999998
or with help of some UI client edit 'expires' column in admin_passwords table to 1999999998 (i changed all lines to affect all users)
2) Clean your browser cache and coockie.
3) Login to Magento. Enjoy it!
