How to disable occasional password

Pasi

I have a business account created with computer 1. It's the master account manager.

I have a computer 2 which is has to be contacted.

Contacting with computer 1 to 2 goes well, no problems and no passwords asked since you've logged in.

I have computer 3 which has to have same easy connection to computer 2. Everytime I try to contact comp 2 with comp 3, it asks password shown to comp 2. It's the occasional password in comp 2 which changes daily. Then I will have to connect comp 2 with comp 1 to see the occasional password before I can have connection to comp 2 with comp 3.

Question: How can I disable comp 2 occasional password so I could connect to it with the same password every day?
