How to log in to MikroTik for the first time
- Connect your PC or laptop via Ethernet cable to any LAN port on the MikroTik device.
- Set your computer’s IP to the same subnet, such as 192.168.88.2.
- Open your browser and go to http://192.168.88.1 or use WinBox to connect.
- Enter admin as the username and leave the password blank, or enter the password found on your router’s sticker.
- Once logged in, change the default password immediately for security.
When the default password does not work
If you cannot access your router using the default credentials, it might have been changed. Here are possible reasons and fixes:
- The router was previously configured with a custom password.
- A factory reset was performed without restoring the default configuration.
- Your RouterOS version uses a unique device password instead of a blank one.
How to reset MikroTik password
To reset your MikroTik router to factory defaults:
- Power off the router.
- Hold the RESET button while powering it on.
- Keep holding for about 5-10 seconds until the ACT light blinks, then release.
- Wait for the router to reboot with the default configuration.
After resetting, you can access the router again via 192.168.88.1 with username admin and no password.
Security recommendations
- Always change the default password after your first login.
- Disable unused services such as Telnet or FTP to reduce attack surface.
- Keep RouterOS updated to the latest stable version.
- Backup configurations regularly.
