I recently had a
client ask me to send out an email blast via Mailchimp. I went to sign in, and
my password no longer worked. I clicked the link to reset it and find out that
the client changed my account to be under his email address.
Me: Hey, looks
like you changed the account details on Mailchimp.
Client: I did!
Me: Would you
mind sending me the new credentials then?
Client: Why do
you need those?
Moral of the story,
even if you set up an account for a client, never share the login information
unless you absolutely have to.
