SSH : is it possible to replace expect "legacy" login with SSH key sign in ?

SSH : is it possible to replace expect "legacy" login with SSH key sign in ?

At our shop we have several Linux boxes on which I would like to implement check through SSH. At present I am not satasfied at all with the CLI monitoring. SSH key sign in is so easy and robust, I fear the present solution in opmanager is unstable and risky towards security and a simple prompt change.

Any tips on this ?
