Hi everyone. Do you know a reputable & reliable service or tool to manage employee accounts at Github/Slack etc?<p>People join my company: I add their Github handles to a group at Github, Slack and a few more including iOS Dev team.<p>I am looking for a tool that would give me an overview on all these accounts, showing who has access where with what account, so that whenever someone joins or leaves the company I can manage them easily and never forget about any of them.<p>I know SSO would partially solve the problem, but I am hoping there is a solution that doesn't require it.
