How can i hide administrator login url in joomla?
Is there a simple way or i need to install an joomla extension?

This question has been asked several times at the forum, for example Does hiding Admin Panel URL help with Security?

In addition to the options presented in the earlier topic, check the cPanel provided by your host. Its section 'Files' may have the option 'Directory Security', which allows you to add to the administrator folder a separate username and password, which are independent of the Joomla installation:

Set a password to protect certain directories of your account. When you enable this feature, a user that tries to open a protected folder will be prompted to enter a username and password before they can access your content.

I would install this https://www.akeeba.com/documentation/admin-tools.html This will allow you to add a suffix to the administrator link and also set an additional password to secure the page.

You can password protect the admin with htaccess rules.

I'd also enable 2-factor authentication (doesn't hide the URL but gives extract login protection).

It is not recommended to renaming the administrator directory. I don't know if it's the case now, but Admin Tools did *allow* renaming of the /administrator folder but it was not a supported feature by the Akeeba team; if it broke your site, they were not in a position to help fix it (it's an use-at-your-own-risk feature) I'm not exactly sure why it was even an option if it's that risky and it's clearly labelled as such.

Joomla has sufficient 2FA built in.

Hiding or changing the URL would be not recommended, as some extensions may hard-code the /administrator URL / name, and therefore break if you rename the folder to anything other than leaving it as /administrator.

Best way is as already mentioned - 2FA and/or the secret code appended to the URL and/or .htaccess protection on the folder.
