Thanks, it helped but I think it will happen again later and this isn’t supposed to happen

I think it will happen again later

Why? Have you asked your hosting company about this issue?

This is not about the host. I have about 15 websites on the same host, some of them created with WordPress months ago and they work perfectly. The problem is with the new ones I created. Like I wrote previously, I am absolutely sure that I wrote the correct password and it didn’t work. It’s like someone’s changing the password or the system changes itself.

So have you tried one of the other methods in the article I linked above? If “someone is changing” your password, you should look into whether your site has been hacked.

Also, some hosting companies have instituted extra login security measures – https://www.ads-software.com/support/topic/brute-force-attacks-and-wordpress?replies=2
