Behind GitHub’s new authentication token formats (via) This is a really smart design. GitHub’s new tokens use a type prefix of “ghp_” or “gho_” or a few others depending on the type of token, to help support mechanisms that scan for accidental token publication. A further twist is that the last six characters of the tokens are a checksum, which means token scanners can reliably distinguish a real token from a coincidental string without needing to check back with the GitHub database. “One other neat thing about _ is it will reliably select the whole token when you double click on it”—what a useful detail!
