Why can't you push to the server?

Question

git

There is a repository > one company. I need to complete a test task. Job done, but I'm having trouble committing and pushing the code.
First, I cloned this repository locally. Then, I added all the changed files, made a commit.
And so, I push:
git push -u origin master
I get:

Password for 'https://[email protected]': 
remote: Unauthorized
fatal: Authentication failed for 'https://[email protected]/choolexam.git/'

The password is correct. I don't understand what I'm doing wrong

Answer 1

If you have studied the task as carefully as the introductory one on the repository page, then I recommend that you do not show it to anyone. In the same place, in English, in black and white it is written:
All these letters, as well as the rest of the information on the main one, you should have carefully read before starting work.
You have read-only access. Even if you were allowed to push there. Yes, and in master.
I hope you didn’t write to them about this problem, since such actions are already a reason to choose a person who is more competent and attentive than you.

Answer 2

No, the password is not correct.
Clearly they say - Unauthorized.
Either the user, or the password, or the server.
