Re: Two Factor authentication and changing passwords

If *passwords are /not/ allowed* when using SecureID this would be
accurate.
If ssh keys are not allowed to gain access to the serves protected by
SecureID and *passwords are not* allowed this would be accurate.
If the only access method was SecureID, and the passwords were used as a
second level and they could be 100% sure that the person trying to
access the account of John_Smith  was indeed John_Smith and not
Fred_Jones I would say they have a leg to stand on.

In general whenever passwords are used they should expire in a
reasonable period time even with SecureId.

for how often passwords should be changed if two-factor authentication
is used.

I am working with a client who thinks that using SecurID tokens means
they should never have to change their passwords but I am not
comfortable with this.
