Is there any word in English, which describes combination of username and password?
Let's say, I want to say Enter your "this_word", meaning Enter your username and password.
EDIT:
I'll exlpain, why I need this (because I see that it's being asked), though I see some answers, which fit my requirements. I'm a software developer (freelancer) and I'm creating a Desktop application, where login/password pair is present. But after releasing the first version of application I got the feedback, that It isn't clear for 'stupid' (no offense, just expression) users what they have to enter. So before it was like:
|username (placeholder)|
|password (placeholder)|
and after the feedback I want to change it to something like
Enter your Google 'word'
|username (placeholder)|
|password (placeholder)|
so, that's it.
