# Frequently Asked Questions
### 1. What are the default network credentials?
- SSID: GhostNet
- Password: GhostNet
### 2. What are the default credentials for the web interface?
- Authentication is off by default in v1.8.1.
- If you enable it with webauth on, the defaults are:
Username: GhostNet
- Password: GhostNet
### 3. How do I access the web interface?
- Connect to the GhostNet WiFi network.
- Open your browser and visit:
[ghostesp.local](http://ghostesp.local)
- or [192.168.4.1](http://192.168.4.1)
### 4. Why don’t the default credentials work for the web interface?
- The web interface uses the same credentials as your WiFi AP.
- If you’ve changed your WiFi SSID or password, your web interface credentials also change.
- To disable authentication, open the GhostESP terminal or a [serial console](https://ghostesp.net/serial) and run webauth off, then restart the device.
Note
The firmware has a subtle password-length mismatch: the AP code falls back to the default password unless the saved password is longer than 8 characters, while web authentication treats passwords of length 8 as valid. If you set an exactly 8-character password you may see the web UI and AP use different credentials; use a password longer than 8 characters to avoid this.
### 5. How do I flash my board?
- See the [Installation Guide](/v2.1/getting-started/installation-guide/).
- Use the web flasher at: [https://ghostesp.net/flasher](https://ghostesp.net/flasher)
### 6. Can I upload custom Evil Portal HTML over Serial or from my Flipper Zero?
- SD Card: Place custom HTML in /ghostesp/evil_portal/portals on your SD card.
- Flipper Zero App: You can upload simple HTML (max 2048 bytes) directly via the app (v1.4+ and firmware v1.7+).
### 7. My board isn’t currently supported. Will you add support?
- Unless something is said otherwise, no. Feel free to do it yourself—we accept and appreciate PRs.
### 8. Why does my connection to the GhostESP AP drop when issuing WiFi commands?
- The ESP32 can’t operate as both an Access Point and WiFi Client at the same time.
Switching modes will disconnect your device from the AP.
### 9. I’m not seeing any output when connecting via Serial.
- The firmware is silent unless a command is running.
- Try sending the help command to verify your connection or reconnecting; sometimes you will have a bad connection.
### 10. Why won’t my SD card work?
- “Generic” firmware builds include SD card support by default; use sd_config to see the pins or sd_pins_spi <cs> <clk> <miso> <mosi> to set SPI pins and sd_save_config to save the pin config to SD card.
- Ensure your SD card is formatted as FAT32.
- Try using a SanDisk brand SD card 32GB or less.
