Button for registration and login to wordpress without widget and plugin, what options?

Question

WordPress

Hello. faced such problem: it is necessary to put buttons on an input and registration. If you use the meta widget, then entering the registration button changes to the site management button, even if you are not an admin. If there is a way to fix this, please let me know. Among the plugins, I did not find anything normal either. How can I make links to enter and register? Do you have any advice or is there a solution? Thanks
