Credential storage options in Git - Step-by-Step Execution

Process Flow - Credential storage options

User runs git command needing credentials

↓

Check credential helper configured?

No→Prompt user for username/password

Yes↓

Use stored credentials from helper

↓

Authenticate with remote

↓

Success or failure

↓

If success and helper set to store, save credentials

↓

End

Git checks if a credential helper is set to retrieve stored credentials; if not, it asks the user. After authentication, it may save credentials for future use.

Execution Sample

Git

git config --global credential.helper store
git clone https://example.com/repo.git

This sets Git to store credentials in plain text and then clones a repository, prompting for credentials once and reusing them later.

Process Table

Step	Action	Credential Helper Used	Credential Source	Result
1	Run git clone command	store	Check stored credentials file	No credentials found
2	Prompt user for username/password	store	User input	Credentials entered
3	Authenticate with remote	store	User input	Authentication successful
4	Save credentials to store	store	Write to ~/.git-credentials	Credentials saved
5	Next git command needing credentials	store	Read from ~/.git-credentials	Credentials used automatically
6	Authenticate with remote	store	Stored credentials	Authentication successful

💡 Credentials stored and reused; no further prompts needed

Status Tracker

Variable	Start	After Step 2	After Step 4	After Step 6

credentials_in_memory	none	user input	stored in file	retrieved from file
authentication_status	none	pending	success	success

Key Moments - 3 Insights

Why does Git ask for credentials the first time but not the second?

At step 2, Git prompts because no stored credentials exist yet. After step 4, credentials are saved, so at step 5 Git reads them and uses them automatically.

What happens if no credential helper is configured?

Git will prompt for credentials every time because it has no way to save or retrieve them, as shown by the 'No credentials found' in step 1.

Is storing credentials with 'store' helper secure?

No, 'store' saves credentials in plain text (~/.git-credentials), so anyone with access to the file can read them. This is important to know for security.

Visual Quiz - 3 Questions

Look at the execution table, at which step are credentials saved to disk?

A Step 4

B Step 5

C Step 2

D Step 6

💡 Hint

Check the 'Result' column for when credentials are saved to ~/.git-credentials

According to the variable tracker, what is the value of 'authentication_status' after step 4?

A pending

B success

C none

D failed

💡 Hint

Look at the 'authentication_status' row under 'After Step 4' column

If the credential helper was not set, what would happen at step 5?

A Git would use stored credentials automatically

B Git would fail without prompting

C Git would prompt the user for credentials again

D Git would skip authentication

💡 Hint

Refer to the explanation in key moments about no credential helper configured

Concept Snapshot

Git Credential Storage Options:
- Use 'git config --global credential.helper <helper>' to set storage method
- 'store': saves credentials in plain text (~/.git-credentials)
- 'cache': stores credentials temporarily in memory
- Without helper, Git prompts every time
- Stored credentials speed up authentication and avoid repeated prompts

Full Transcript

When you run a Git command that needs your username and password, Git first checks if a credential helper is set. If it is, Git tries to get your saved credentials from there. If no credentials are found, Git asks you to enter them. After you enter your credentials and authentication succeeds, Git can save them using the helper you configured. For example, the 'store' helper saves them in a plain text file on your computer. Next time you run a Git command, Git reads your saved credentials and uses them automatically, so you don't have to type them again. If no helper is set, Git will ask you every time. This process helps you work faster but be careful with security when choosing how to store credentials.
