From the list of suggested software for managing WM purses select the following:
Registering WM Keeper Light (authentication with the help of digital certificate).
Accept the WebMoney Agreement, enter your password and click the “Register” button.

After installation of the certificate, you will be assigned a WM identifier required for logging on to the system. Be sure to remember your WMID, or better still, write it down.

To install the certificate to your storage, click the “Install this certificate” link. Agree to install the certificate to the storage, and also set (if you have not done so previously) a master password to protect your certificates.

Click the “Launch” button (double-click it), choose “Certificate x.509” as the authorization method and click the “Login” button. In the window requesting the certificate, select your WMID. Click the “OK” button.

To launch WM Keeper Light again, you can use the “Login to Keeper Light” link on the main page of the site at www.wmtransfer.com
Attention! After the next reinstallation of the browser or operating system, you will lose your personal digital certificate and you will not be able to access the purse management page. To avoid such problems and protect your WM Keeper Light from unauthorized usage, we recommend to export the certificate from the certificate storage to the local computer, create a backup copy of the certificate and re-install it to the storage in accordance with our recommendations. You can find more details on how to correctly save this certificate as a file and then re-install this certificate back to the system by visiting this site.
Another important note! When importing the saved personal certificate in Opera using the standard window, go to: Tools → Preferences → Advanced → Security → Manage certificates. The browser may start to hang and the certificate will not be imported. But if you choose “File”→ “Open” in Opera and select the saved certificate on your disk, then it will be successfully imported.
(Do not forget in the “File Types” list of the “Open” window to select the “All files” option to see the saved certificate on the disk).
Tested on Opera versions 9.60 – 9.64
