I think this is what OP meant by “linking” their account.
And it does come in handy when solving account issues.
An EVE Online account that has been created through STEAM does not have an account name
or password, and can therefore not be logged into outside of STEAM or easily used as
target account for character transfers.
It is however possible to set up an account name and password for all Steam integrated
EVE accounts through the Account Management pages.
Log into “Account Management” by selecting the “Sign on through STEAM” button
Once signed in, hover over the “Account” drop down and select “Create EVE Username”
Once set, it will be possible to log into the account using the new account name and
password within the game launcher as well, should a log in through STEAM not be possible
for any reason
Sorry about the necropost, but this is a continuing problem.
