Is there a way to have a "password profile" (i.e. central password) for use in SSH sessions?

[AustinHarisch]

I SSH to switches all the time, and I have to configure my password for each and every switch that I connect to. That password is managed by a TACACS+ server, which means if I change my password, I'd have to update it for every switch I have an entry for. Is there a way to have a "password profile" that I can apply to every SSH connection so I'd only have to update it in one spot? i.e. I'd create a new profile with my TACACS+ username and password and call it "TACACS Credentials" or something like that. Or, if that isn't possible, is there at least a way for me to edit the config in bulk so I can change all of the passwords at once?
