Git clone without username and password

Question

I'd like to use git clone https://... without using username and password, it doesn't work on my server.

Command : sudo git clone https://gitlab.com/****/****.git

Issue : They ask me the username and password.

Using SSH, they ask me the passphrase, and I don't want to input something after git clone.

Any ideas?

Edit #1

Command : sudo ssh-keygen -p -P "myoldpassword" -n "" -f /root/.ssh/id_rsa.pub

Result :

To remove the passphrase from your ssh key you need to run

$ ssh-keygen -p [-P old_passphrase] [-N new_passphrase] [-f keyfile]

There is also the option of using ssh-agent, which can cache the passphrase for some time.

Answer 2

Just use chmod 400 /root/.ssh/id_rsa.pub. This will make your key read-only, and will allow you to use it.
