AuthenticatorAccount.TryParse("otpauth://totp/ACME%20Co:john.doe@email.com?secret=HXDMVJECJJWSRB3HWIZR4IFUGFTMXBOZ&issuer=ACME%20Co&algorithm=SHA1&digits=6&period=30", out var account); 
var password = account.GeneratePassword().Password;

From custom parameters

using (var hmac = HMAC.Create("HMACSHA1"))
{
    var length = 6;
    var time = DateTimeOffset.Now;
    var period = TimeSpan.FromSeconds(30);
    var secret = Encoding.ASCII.GetBytes("12345678901234567890");
    var password = new TimeBasedAuthenticator().GeneratePassword(length, hmac, secret, time, period).Password;
