This page describes FAQs regarding password expiration.

The password expiration is calculated starting from the date and time when the user changed the password, not the date and time when the administrator changed the setting.

For example, assume that User A changed the password on March 1st at 10 AM.
Then, on March 25th, Kintone Users & System Administrator changed the password expiration setting to 30 days.
In this case, the password for User A will be valid from "March 1st, 10 AM" to "March 30th, 10 AM" which is 30 days after the start date.

When the number of days remaining before the password expires is five or less, a message appears on the page after login that displays the number of days remaining and prompts you to change the password.

You cannot log in with an expired password.
If you try to log in, you are directed to the "Reset Password" screen.

If password expiration should not be applied to certain users, you can set their passwords to never expire.

Method 2: Disabling Password Expiration for Particular Users

Even when the above setting is made, users are requested to change their temporary passwords if the Kintone Users & System Administrator enables the "Force Password Change" option and then changes users' passwords.
