I use Arduino Serial Monitor to enter WiFi login and password. The next time I run a program I don't need to enter the same data. I can press "enter" key twicely because Serial Monitor remember these inputs (I think so).
I would like to program wait ten seconds and trigger pressing ENTER key if no data is entered by user. How to do it? I did not find examples with similar implementation.

while (Serial.available() == 0) {

  }

  Serial.readBytesUntil(10, password, 50);

  Serial.println(password);

When I press enter key without entering any data there is no data output on Serial Monitor but WiFi connection is successful.

I managed with Serial.setTimeout after Serial.begin and commenting these lines:

while (Serial.available() == 0) {     

  }

You use esp8266 module I expect. esp8266 remembers the last STA connection ssid and password and connects automatically at default.

Usual is to do

if (Serial.available()) {

  Serial.readBytesUntil('r', password, 50);

  Serial.println(password);

}

to not block the loop
