  1. Click the lock in the address line.
  2. Click the arrow to the right to dis­play fur­ther infor­ma­tion.
  3. Click More infor­ma­tion.
  4. Click View Cer­tifi­cate.
  5. The fin­ger­print is ver­i­fied com­paring the char­acter set dis­played with a ref­er­ence set which you will have received from your finan­cial insti­tu­tion. If the char­acter sequence read from the cer­tifi­cate and the ref­er­ence sequence received from your finan­cial insti­tu­tion are iden­tical, this is a gen­uine cer­tifi­cate. Please note when com­paring the fin­ger­print type: The sequence and ref­er­ence sequence must be of the same type (SHA-256 or SHA1 respec­tively). You will find our part­ners’ cer­tifi­cate fin­ger­prints on our web­site in our article on Cer­tifi­cate Checking.

Instruc­tions for alter­na­tive browsers:

You can check the authen­ticity of a cer­tifi­cate which an SSL con­nec­tion is based on with the help of the cer­tifi­cate fin­ger­print. A fin­ger­print is usu­ally dis­played as a hexa­dec­imal char­acter string con­sisting of the let­ters A-F and the num­bers 0-9.
