Remember to enter your ESET-issued Username and Password exactly as they are written:

  • The Username and Password are case sensitive
  • The hyphen in the Username is necessary
  • The Password is ten characters long and all lowercase
  • If you are copying and pasting, make sure you don't select an extra blank space
  • We do not use the letter L in passwords (use the number one (1) instead)
  • A big '0' is the number zero (0); a little 'o' is the lowercase letter o
