GitHub Made Crystal Clear · chapter 2: Your first repository
Pick the credential by the job, not by habit

The dashed box at the bottom is the option that no longer exists, and the side panel is why every GitHub credential is recognizable on sight.
Below: the paragraph from the book that builds this idea, then the diagram itself (Figure 2.2), and a recap. About a minute of reading.
Figure 2.2 answers the question by task instead of by preference, and carries the token-prefix table alongside it. Those prefixes matter more than they look: every GitHub credential starts with a known string, which is precisely what makes a leaked one machine-detectable. Chapter 12, Security you already have, is built on that fact.
Recap
- The idea: The dashed box at the bottom is the option that no longer exists, and the side panel is why every GitHub credential is recognizable on sight.

- Go deeper: the chapter builds this step by step, with recipes and sources at the end.
This diagram is one of many in GitHub Made Crystal Clear.
