What is the default username and password?

• A. admin with no password
• B. admin with password
• C. root with no password
• D. guest with no password

Answer: (A)

Default access to MikroTik RouterOS uses the user name admin with an empty password. On first login after boot, you can sign in by entering admin and leaving the password blank, and you’ll be prompted to set a password right away. This is why admin with no password is the correct choice. The other options don’t match how MikroTik devices are typically accessed by default—there isn’t a root login, and while a guest account exists, it’s not the standard default login. Remember to set a strong password during or immediately after first login for security.
