Same RSA key on multiple PCs

Question

Can I use my RSA private key on multiple computers i.e. my desktop and laptop. Or do I have to create a unique key for each computer I own, and add their respective public keys to necessary servers/programs.

You can, but you shouldn't.

Each device should get its own keypair. This makes recovery from a lost or stolen device much easier.

Although it's technically correct, it's not a good advice. – rvs Mar 24 '16 at 23:10
