Specific Length of OTP Token

[nazarhussain]

Hello,

I am in a situation that requirements are specifically asked for 4-digit OTP. Is there any possibility to generate 4-digit or any specific length OTP?

Your guidance will be much appreciated.

You can pass in the digits option to get this

ROTP::TOTP.new("base32secretkey3232", :digits => 4)
See more at: http://www.rubydoc.info/github/mdp/rotp/master/ROTP/OTP#digits-instance_method

Let me know if that doesn't work for you.
