problems logging in to the launcher

[Derverment]

Скачал лаунчер, ничего не меняя, зарегистрировался, подтвердил всё, запустил лаунчер, написал логин и пароль, выдаёт такую ошибку: недопустимые учетные данные. Неверное имя пользователя или пароль. Зашел на сайт написал тот же пароль и логин, смог зайти.
Downloaded the launcher without changing anything, registered, confirmed everything, launched the launcher, wrote the username and password, and returns the following error: invalid credentials. Invalid user name or password. I went to the site and wrote the same password and username, and was able to log in.

our launcher requires the Mojang credentials to log in, same as every other legit modded launchers for Minecraft.

you need to own the Java edition of Minecraft and have a premium Mojang account. that's the account you use to log in through Technic launcher

As you are confused, I do not have the funds to buy a license for minecraft, I thought you have everything simple.
