You can also create your own generators with a specific character set as shown below:

//	Create generator with specified character set
g := password.NewGenerator(&password.CharSet{
	Lowercase: "abc",
	Uppercase: "ABC",
	Digits:    "012",
	Symbols:   "",
})

//	Generate a password consisting of
//	5 lowercase, uppercase letters and 5 digits
pass, err := g.Generate(5, 5, 5, 0) //  output: 1Cc1c02cAB2CBba

//  Generate a password of length 15
pass, err := g.GenerateLength(15)   //  output: a0BC1B1cbA1a10B
