If you forget your password, first make sure that you enter it correctly! (Has the CapsLock key been pressed? Is the correct keyboard layout enabled?) You can enter a password in the "login" field or any other and make sure that you enter the password correctly!
If you still cannot log in, write a message to the info@infinity-mlm.com in a free form, with your name, phone number specified during registration, Email, ID number and your name or number of the sponsor, and wait for the response letter
