Speakeasy | receive real time feedback

I did a TOTP (unique time-based password) with SpeakEasy, everything works fine, I put a condition (at the end of the code) to validate a token and then redirect it to a hidden page but it doesn't work, and I don't do not know why. Thank you for your help

I'm using the following library to implement two-factor authentication:

https://github.com/speakeasyjs/speakeasy

The library produces the following QR Code:

When I scan the code in Google Authenticator and Duo, both apps produce different tokens.

The speakeasy library only recognises the Google Authenticator token as valid.

Why does the same QR Code produce different tokens in the two different apps?

I've a strange problem with speakeasy OTP verifcation and the OTP should be expired after 2 minutes.

Generate token

I have a 2FA code in my nodeJS server application that utilizes speakeasy module to verify whether the passed key is valid or not. I am using google Authenticator app on the client side. I am using a secret key = "A0B0C0D0E0F0A1B1C1D1E1F2". This works on Android devices well. However, when I try the same on an Iphone, I face the following issues:

1. Google Authenticator App on Iphone does not allow me to add the secret "A0B0C0D0E0F0A1B1C1D1E1F2". It seems it has some native rules wrt secret keys.
2. Even when I enter a secret key that the Iphone allows, speakeasy.totp code is not able to verify, and always returns a FALSE.

I created a Python 3 script using the BeautifulSoup library. What it does, is going to the duckduckgo search engine using the following url: https://duckduckgo.com/?q=searchterm and then, it will display to me all the websites in the first page.

Here is the code and it is working perfectly:

error: bundling failed: "Unable to resolve module crypto from myproject/node_modules/speakeasy/index.js: Module does not exist in the module map\n\nThis might be related to https://github.com/facebook/react-native/issues/4968\nTo resolve try the following:\n 1. Clear watchman watches: watchman watch-del-all.\n 2. Delete the node_modules folder: rm -rf node_modules && npm install.\n 3. Reset packager cache: rm -fr $TMPDIR/react-* or npm start -- --reset-cache."

Following the suggested steps doesn't seem to do any good.

Also tried to yarn add react-native-crypto but that didn't help either.

Is it possible to detect the timestep length of a TOTP token/passcode (e.g. 30 seconds vs 60 seconds) when validating that token against the secret key? In other words, is the step time is programmed into the token?

I'm trying to validate TOTP token using speakeasy but my tokens have 60 second time steps vs the default 30 second time steps that the validator expects. So the tokens don't validate unless I specify that the time step is 60 seconds. When turning this into a REST API would I need to require the timestep of the token in question as part of the request?
