| Username | Password | Notes | | :--- | :--- | :--- | | admin | admin | Most common for retail ZTE routers | | admin | password | Common on older models | | user | user | Limited access (user mode) | | (blank) | admin | Leave username empty | If the above don't work, your ISP likely customized the firmware: zte router default username and password
