Given the way passwords are used I see no issue in asking them to be
changed, they are very easy to steal in our current system, so I don't
complain about that.
Ssh keys are a different matter, they are generally much more secure as
they are not easily distributed or easy to steal, and changing them is
no assurance the new ones are not as compromised. (see previous mail)

Storing a public key is not an issue, so the fact I use my key with
different projects has absolutely no bearing on my exposure, zero,
zilch. Unless I store my *private* keys on non-personal machines.
The problem is that blindly changing keys if a contributor is being
careless accomplishes exactly nothing, and just burdens all careful
If you have evidence of contributors being careless with SSH keys the
only recourse is to identify and educate the offenders requiring them to
change those keys and not have a 'hit 100 to educate 1' policy that
serves little or no purpose.
