💡 Hint

Common Mistakes

Using 'store' which saves credentials permanently in a file.

Using 'manager' which is platform-specific and more complex.

The cache helper stores credentials in memory for a limited time, so you don't have to enter them repeatedly.

Common Mistakes

Using 'cache' which only stores credentials temporarily.

Using 'manager-core' which is platform-specific.

The store helper saves credentials permanently in a plain text file in your home directory.

💡 Hint

Common Mistakes

Using 'manager-core' on Windows which may not be installed.

Using 'cache' or 'store' which do not integrate with Windows credential manager.

On Windows, the correct helper is manager to use the Git Credential Manager.

4fill in blank

Fill both blanks to configure Git to use the credential helper that stores credentials for 15 minutes.

Git

git config --global credential.helper '[1] --timeout=[2]'

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'store' which does not support timeout.

Setting timeout to 3600 which is 1 hour, not 15 minutes.

The cache helper can be configured with a timeout in seconds. 900 seconds equals 15 minutes.

5fill in blank

Fill all three blanks to create a Git credential helper configuration that stores credentials permanently and sets the file path.

Git

git config --global credential.helper '[1] --file=[2]/[3]'

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'cache' which does not support file path option.

Confusing file path parts or missing the file name.

The store helper saves credentials permanently. You can specify the file path with --file. Here, the file is ~/.git-credentials/credentials.

Practice

1. Which Git credential helper stores your password temporarily in memory for a limited time?

easy

A. store

B. manager-core

C. osxkeychain

D. cache

Solution

1. Step 1: Understand credential helper types

   Git offers different helpers: cache stores credentials temporarily in memory, store saves them permanently in plain text, and platform helpers like osxkeychain or manager-core store securely.

2. Step 2: Identify temporary storage helper

   The cache helper keeps credentials in memory for a short time (default 15 minutes), so you don't have to retype passwords repeatedly during that period.

3. Final Answer:

   cache -> Option D

4. Quick Check:

   Temporary credential storage = cache [OK]

Hint: Cache means temporary memory storage for credentials [OK]

Common Mistakes:

• Confusing 'store' as temporary storage
• Thinking 'osxkeychain' is temporary
• Assuming 'manager-core' caches credentials

2. Which command correctly sets Git to use the credential helper that saves passwords permanently in plain text?

easy

A. git config --global credential.helper store

B. git config --global credential.helper cache

C. git config --global credential.helper osxkeychain

D. git config --global credential.helper manager-core

Solution

1. Step 1: Recall command syntax for setting credential helper

   The command to set a credential helper globally is git config --global credential.helper <helper-name>.

2. Step 2: Identify helper for permanent plain text storage

   The store helper saves credentials permanently in plain text on disk, so the correct command is git config --global credential.helper store.

3. Final Answer:

   git config --global credential.helper store -> Option A

4. Quick Check:

   Permanent plain text storage uses 'store' helper [OK]

Hint: Use 'store' helper for permanent plain text saving [OK]

Common Mistakes:

• Using 'cache' instead of 'store' for permanent saving
• Confusing platform helpers with plain text storage
• Missing the --global flag

3. What will be the output of the command git config --get credential.helper after running git config --global credential.helper cache?

medium

A. store

B. cache

C. osxkeychain

D. manager-core

Solution

1. Step 1: Understand the effect of setting credential helper globally

   Running git config --global credential.helper cache sets the credential helper to cache in the global Git config.

2. Step 2: Check what git config --get credential.helper returns

   This command reads the current credential helper setting, which will be cache after the previous command.

3. Final Answer:

   cache -> Option B

4. Quick Check:

   Get helper after setting cache = cache [OK]

Hint: Get command shows current helper exactly as set [OK]

Common Mistakes:

• Expecting output to be 'store' or platform helper
• Confusing local and global config scopes
• Assuming no output if helper is set

4. You set your Git credential helper with git config --global credential.helper store, but your password is still asked every time. What is the most likely cause?

medium

A. The credential helper cache is overriding store

B. The platform helper must be used instead of store

C. The stored credentials file is missing or unreadable

D. You need to restart Git after setting the helper

Solution

1. Step 1: Understand how 'store' helper works

   The 'store' helper saves credentials in a plain text file (usually ~/.git-credentials). If this file is missing or unreadable, Git cannot use stored credentials.

2. Step 2: Identify why password prompts continue

   If the credentials file is missing or has wrong permissions, Git will ask for the password every time despite the helper setting.

3. Final Answer:

   The stored credentials file is missing or unreadable -> Option C

4. Quick Check:

   Missing credentials file causes repeated password prompts [OK]

Hint: Check if credentials file exists and is readable [OK]

Common Mistakes:

• Thinking cache overrides store automatically
• Believing Git needs restart after config change
• Assuming platform helpers are mandatory

5. You want to securely store Git credentials on Windows without typing your password every time. Which credential helper should you configure?

hard

A. manager-core

B. store

C. cache

D. osxkeychain

Solution

1. Step 1: Identify platform-specific secure helpers

   On Windows, the recommended secure credential helper is manager-core, which integrates with Windows Credential Manager.

2. Step 2: Compare with other helpers

   cache is temporary, store saves plain text, and osxkeychain is for macOS, so they are not suitable for Windows secure storage.

3. Final Answer:

   manager-core -> Option A

4. Quick Check:

   Windows secure storage uses 'manager-core' helper [OK]

Hint: Use 'manager-core' for secure Windows credential storage [OK]

Common Mistakes:

• Choosing 'store' which is insecure
• Using 'osxkeychain' on Windows
• Expecting 'cache' to be secure and permanent
