1. GitHUb - How to fix this issue?
Step 1 - Create SSH key pair
One of the easiest ways for you to generate a key pair is by running
command prompt and type in the following
(Note - If you do not have ssh-keygen installed on the window then Click here.)
To keep the
ssh-keygen simple, do not enter any key name or passphrase.
1Generating public/private rsa key pair. 2Enter file in which to save the key (/Users/rahulwagh/.ssh/id_rsa): 3Enter passphrase (empty for no passphrase): 4Enter same passphrase again: 5Your identification has been saved in /Users/rahulwagh/.ssh/id_rsa. 6Your public key has been saved in /Users/rahulwagh/.ssh/id_rsa.pub. 7The key fingerprint is: 8SHA256:Okq3w+SesCGLQVToSBQru8RdUZtT2EIIrzH5MQ67DWA rahulwagh@local 9The key's randomart image is: 10+---[RSA 3072]----+ 11|.ooo..+oo. | 12| oo o..o+. | 13|=E = = +. | 14|*oo X o . | 15|.+ = o S | 16|o. + .. | 17|o ..+=+ | 18| o + *++ | 19|. . o.+. | 20+----[SHA256]-----+
Where to find the key pair
The file will be generated at - /Users/rahulwagh/.ssh/
Name of the file - id_rsa.pub
(To generate SSH keys on Windows machine click here)
Step 2 - Adding SSH key to your GitHub account
- Goto your GitHub Account -> Settings
- Then look for SSH and GPG keys under **Account Settings -> SSH and GPG keys **
- After that click on New SSH Key. Assign some meaningful name to your key
- To get the key goto to your command prompt and switch directory path
Windows - C:\Users\rahulwagh.ssh\id_rsa.pub
Linux - /Users/rahulwagh/.ssh/id_rsa.pub
Run the following command
Copy the content of the key
Paste the key inside your GitHub account
Now you can clone your GitHub repo and it will not complain about
email@example.com permission denied (publickey). fatal could not read from remote repository
Benefits of this approach
- You do not need to supply you GitHub Username and password
- More secured
- The process of generating SSH keys is little troublesome.
- If you switch your laptop/desktop then you need re-generate the SSH keys again and perform the same steps onto your new laptop/desktop.
Approach 2 : Using GitHub HTTPS urls
This is one more approach in which you do not need to worry about SSH key generation.
You need following -
- GitHub repo URL with HTTPS (Ex - https://github.com/rahulwagh/example.git)
- Your GitHub Username
- Your GitHub Password
Run the following command to set
1git clone origin https://github.com/rahulwagh/example.git
After that it will ask for your
password, supply your username and password.
Once you are authenticated then you can perform your Git operations.
Benefits of this approach
- You do not need to generate SSH keys
- You do not need to copy your SSH keys to GitHub accounts
- This approach can be used from any Laptop, Desktop. You only need to provide your GitHub credentials with this approach.
- The only drawback which I can see is you need to input your GitHub credentials everytime.
2. GitLab: How to fix gitlab.com: permission denied (publickey) fatal: Could not read from remote repository
2.1 Multiple public keys inside
When you are working with multiple
github repositories then there is high probability that you might have
incorrect public key mentioned inside your
For example I have generated the public key for my GitLab project by the name
But when I checked my
~/.ssh/config file I noticed the incorrect name of public key for the
Here is the content of my
~/.ssh/config file where the public key name is
~/.ssh/id_rsa instead of
1Host gitlab.com 2 Preferredauthentications publickey 3 IdentityFile ~/.ssh/id_rsa
How to fix?
To fix this issue you should correct the public key name -
1Host gitlab.com 2 Preferredauthentications publickey 3 IdentityFile ~/.ssh/id_rsa.gitlab.pub
3. Bitbucket - Permission denied (public key), can’t clone/clone to bitbucket
There could be multiple reasons behind the issue -
3.1 You did not add your local SSH keys to BitBucket Settings
SSH keys could be one of the most probable reasons which are causing the issue while working with your BitBucket repository.
You might see the following errors -
1Permission denied (publickey).
1abort: Permission denied:
or (In case you are working with mercury then you might see this error message)
1remote: Permission denied (publickey). 2abort: no suitable response from remote hg!
How to fix?
Before we start debugging the issue, let’s first debug the issue to know the exact reason behind this error.
Run the following command from your terminal (put your correct repository name) -
1ssh -T firstname.lastname@example.org 2
The above command should return you with
Username and in case you did not see your username then you need to Create SSH keys and add to your BitBucket account.
Step 1 - Create your Public SSH Keys
Step 2 - Goto
Your Account -> Manage Account -> SSH Keys
Step 3 - Click on
Step 4 - Paste your key which you have generated in Step 1.
Step 5 - Finally click on
It should work after adding the SSH keys to your BitBucket account.
(Note - Here are some official links from bitbucket if you are interested more - click here)
3.2 Permission on your bitbucket directory
There could also be a possibility that you do not have permission to access the BitBucket repository. Check with your bitbucket administrator with regards to your permission.
If it is the case of permission then your bitbucket administrator could grant the permission.

1.4 Where to find the key pair
The file will be generated at - C:\Users\rahulwagh.ssh\id_rsa
Name of the file - id_rsa
4. How to fix(GitHub)-Support for password authentication was removed. Please use a personal access token instead
GitHub has recently announced their migration to use token-based authentication which means you can no longer use your username and password for GtiHub authentication. You need to create personal access token to continue use of your GitHub Repository.
Here is my private GitHub repository which I was trying to clone and prompted with the error message -
Before fixing the issue lets try to understand how do you clone your Git Repo - https:// or email@example.com
This issue is very much dependent on the way you clone your repository.
1. firstname.lastname@example.org:rahulwagh/jhooq.git - If you are using SSH way of cloning the repository then you will not face issue related to personal access token. Because when you use SSH way of clonning then you should always create SSH Keys and copy public SSH key to GitHub SSH and GPG keys
2. https://github.com/rahulwagh/jhooq.git - If you are using HTTPS way of cloning the Git Repository then you will be prompted with username, password and after entering the username and password you will be thrown with error Support for password authentication was removed. Please use a personal access token instead
How to fix the personal access token for GitHub Repository
- Login to your GitHub account from the web browser.
- Goto -> Profile Pic -> Setting
- After that you should look on the left navigation panel and there should be an option of Developer Settings
- Aftr that it will redirect you to the new page where you will find an option Personal Access Token in the left navigation. You should click on it -
- Then next on the right side of the screen you have an option to Generate New Token -
- Enter the token name along with the scopes -
- Finally Generate Token
- Now Copy the generated Token
- Go back to terminal and re-issue the Git Clone command and instead of password input the access token
It should fix your issue of - “Support for password authentication was removed. Please use a personal access token instead”
Advantages of using Personal Access Token
- Strong - The Personal Access Token are randomly generated string which contains all possible combination of literal, number, upper case, lower case and special symbol. So it is really hard for brute force attack.
- Better Scoping - With personal access token you can control the access level at granular level.
- Multiple Personal Access Token - You can more then one personal access token so that you do not have to share password with anyone else.
- Revocable - You can easily revoke the access to repository by deleting the personal access token.
