How can I execute "git push" command without inputing password again?

Hi,

I’m a new user of Gitlab, there is a question haunts me for a long time. When I push some code from the local side to the server, it always reminds me to input the passphrase for ssh key. For the convenience, is there any way to store this passphrase as a default value and won’t need input again once verified?

Many thanks in advance.
