Hello, I noticed that there are generate-password libraries and password-generator for random password generation. But importing a library just for this might not be a good idea. Is there any way in the node itself to do this?
Generate random password

There is a well-known known technique that does this in a practical way:
function gerarPassword() {
return Math.random().toString(36).slice(-10);
}
In this case, you generate a password by converting to base36 and then using only the last 10 characters.
An example application and 10 tests would look like this:
var testes = Array.apply(null, Array(10)).map(gerarPassword);
console.log(JSON.stringify(testes));

I would use Math.random combined with toString(36)
Math.random().toString(36).substring(0, 7)
Parameter 36 passed to toString , must be an integer between 2 and 36 specifying the basis used to represent numeric values.
Using substring we are limiting the number of characters that will be returned. That is, I generated a random password with a maximum of 7 characters.
