Passwordless authentication with Amazon Cognito | Amazon Web Services

[@niv8880]

Would love to know how to add a flutter client to this instead of React. Anyone got any tips?

Great video! I really like the way the problem is described and the solutions being avaible pointed out to manage them. If I may I would like to give you feedback on your audio. Using a tscz-filter would really boost your audio and make the experience way smoother and the content itself more accessable. Most dessing- or tscz-filter plugins that accomplish that are for free.

This is very inspiring !! I will start to integrate it immediately.

Thanks! 💪 😎

May I kindly look for your experience, which will help during the integration? I am integrating this into React app and getting '- error node_modules/amazon-cognito-passwordless-auth/dist/client/react/components.js (275:0) @ eval - error ReferenceError: navigator is not defined at Array.find () null'. Any directions I should dig deeper to check on this? PS: I got the e2e example installed and it works fine. Got the AWS infra also.

The issue is I am using it in JSX files?

Thank you for the video with clear step-by-step instructions. Very helpful! I deployed this and am getting a strange 400 error message: Sign-in as another user 1 validation error detected: Value 'us-east-2_lxLV5Do89' at 'clientId' failed to satisfy constraint: Member must satisfy regular expression pattern: [\w+]+ Anyone else experience this error?

Hi Chris, just wanted to follow up regarding your question. I forwarded this to the appropriate team, and this was their response: The SA says "This looks like a user pool id: us-east-2_lxLV5Do89. So the user I think mistakenly uses a user pool id where they need to pass a client id". ^DC
