Espressif Systems ESP8266 / ESP-01 Wi-Fi Module — AT Firmware Default SoftAP — Default Password
Default username and password for the Espressif Systems ESP8266 / ESP-01 Wi-Fi Module — AT Firmware Default SoftAP: (blank) / (blank). Learn how to log in at 192.168.4.1 and how to change the default credentials.
Modules running Espressif's factory AT firmware (ESP-AT) enable a SoftAP by default alongside Station mode. The SoftAP SSID follows the pattern 'ESP_XXXXXX' (last 6 hex digits of MAC address) with NO WPA passphrase — the AP is completely open. The SoftAP gateway/management IP is 192.168.4.1. Use AT+CWSAP? to query and AT+CWSAP= to change. Applies to ESP8266 and ESP32 with Espressif AT firmware only — custom firmware (NodeMCU, Arduino, MicroPython) does not use this default.
