Hello, I wanna ask something. Is it possible to change the default of totp generated from the authenticator app to become a 10m Period totp code? Because in my code, all OTP that are generated is for 10m period (Message, Email, etc) thats why, I need all verify code to be a 10m period totp code, where 30m totp code cannot be used to verify 10m totp code, so all code that is generated from GA is failed, but if I change all verify back to 30m GA can be used again. Anyone has a suggestion? Thankyou

@bagas can you setup your code-accepting logic to accept any otp codes within 5 minutes +- window?

yes you can, change the 30 seconds parameter in the function call to any number you want and on verify the number generate a number based on the new logic you changed
