What to Do When Client Certificates on Users' Mobile Devices Expire
When client certificates on users' mobile devices expire, you need to do one of the following. These actions should be performed by Kintone Users & System Administrators.
To Continue to Use the Client Certificate Authentication
If users want to continue to use the client certificate authentication after the expiration dates of their client certificates, you need to re-issue their client certificates. You cannot extend the expiration dates of existing client certificates.
For details on how to re-issue client certificates, see the "Issuing Client Certificates to Users Whose Client Certificate Will Expire Soon" page.
To Disable Accesses to Mobile Devices
To disable accesses to mobile devices after the expiration dates of client certificates, do one of the following.
Change passwords/Deactivate client certificates
Changing the password causes the user to be logged out and Kintone is no longer accessible on the device. This also prevents Kintone Mobile from sending push notifications to the lost device.
In addition to the password change, it is also necessary to deactivate the client certificate.
Deactivate the user
You can also disable access to Kintone by deactivating the user in Kintone Users & System Administration.
