Login error "Wrong password"
The passwords on all accounts are correct.
After the latest updates, Facebook most often does not allow you to log in to your account with the correct password if the IP country differs from the account country.
If you encounter a problem when logging into your account: "Incorrect password", then most often the problem is in the proxy (or lack thereof). To avoid this, you need to use an IPv4 proxy of the account country and an anti-detection browser. In extreme cases, you can log in via cookies or restore your password via email.
