Occasionally I need to give other developers access to Super Administrator. I've worked with all of mine for several years but, I'd like to eliminate the temptation to copy my WPMUDEV API key.
Can we just have a green box that shows "API Key Entered" ?
It could be encrypted in the database using the same process as passwords.
Hmm, it would be nice to have a place in our WPMUDEV account dashboard that shows the sites using our API key. If a key suddenly starts getting used on hundreds or thousands of websites, that would be a good indication of it being "shared". I don't think that is too intrusive or violates any privacy issues, you expect to be paid for your work.
Since I have hundreds of sites too, the API key entry should send a response to WPMUDEV that it was used on a multisite installation.
