Why do I encounter a Security Warning Message when I login to my cpf Online Services or other online application?
The transaction you're performing makes use of a Secure Socket Layer (SSL) digital security certificate. This allows you to conduct safe e-transactions with 256-bit encrypted SSL connections.
Essentially, this digital certificate is an electronic document which your browser uses to authenticate our server and initiate the encryption processes. The certificate is like a stamp of approval that also carries the information needed to activate the SSL process.
