When you register in WM Keeper LIGHT you obtain a personal certificate and the response to it is saved on the server. The validity of the certificate is limited to 1 year. Upon termination, if you do not renew it, you will not be able to access your purses. However, the certificate will remain installed in your browser and you will still be able to export and import it as shown on this page.

During registration your contact e-mail address is requested. Two weeks before the expiration of the certificate an automated e-mail message will be sent to your address to remind you about certificate renewal with the corresponding link. In addition, a notification of the available renewal service will appear in your purses. Open the link, sign-in with your expiring certificate and follow the instructions on the page. You will see the following link:

However, the renewal of the certificate is only available within the stated time period. Either of the above pages will provide a warning.
