Amazon Cognito Beginner Guide

If you have users using OTP and want to move over to Cognito and ensure they can also log in user SSO, how do you do that?

I ran into a very strange error. I created a user pool so that I could implement phone number otp verification. I am able to generate OTP and also verify them. but when I try to fetch the user from the user pool it says : ResourceNotFoundException: User pool ca-central-1_xxxxx does not exist. I am 100% sure that poolID is correct. I create few new user pools with exists IAM roles and also created a new user pool with a new IAM role. nothing seems to work & I can't find an answer on the web as well.
can some help please.

Great video, thank you very much for this! ❤

brooo I have been following your YT channel and all the information you share is AMAZING. Thanks a looot

dude, this video is amazing

Thank you so much!

Wow, clear points in the goal, thanks for this a very good illustration.

Thanks you this video is great explain the concepts and core. But i could to show examples using programming languages, and explore more about integrations app using examples

Simply amazing. Thank you

How to connect Cognito with Spring boot application ?

You sir, should be getting paid by AWS for these videos!

This was such a great explanation and lucid intro to Cognito. Like seriously, 10/10 job. Thanks again, I will definitely be liking and checking out your other videos 👍

Would appreciate a hands on coding video using cognito

Gold

👏

Dude!! You’re good at this. You reduce the complexity of cognito, by an order of magnitude.

This is really good, thanks a ton.

nice. thanks

Nice video, but using implicit flow and / or tokens in url is antipattern this days....

Thanks for the video. Could you also make one about how ECS is integrated with ALB and API Gateway with Cognito? Thanks

Very well, slow and detailed. Thank you

Excellent explanation! Thanks for this nice video. I have a question here. I am beginner so not much knowledge however how to setup AWS Cognito (with SSO) for multi-region considering DR as the critical requirement.

Thanks for the video. Really loved how you explained it for practical use as well.

This all goes well when using a hosted UI. If I need to use my own authentication UI (for different languages) it becomes hell of a mess.

Thanks for this brief explanation. It was very informative.
Do you have more videos about AWS Cognito, like a hands on integration into actual applications?

Nice video

Thank you so much bro, really helpful video. Your channel is the main resource i look when i have any doubt in aws.

can I use cognito for the applications hosted in onprem data center, VM Ware OR any other Private Cloud ?

This presentation of the Cognito service is brilliant.
All the important details fit in 25 minutes.
Thank you.

Not being able to signout from the amazon provider. Automatically being signed in, instead of showing the sign form. Any Solutions?

OMG . Are you kidding me ? . I cant believe such an excellent presentation is available on this topic . it has got all what i need , Hats off to you man

Great summary, thank you. They should link this directly from the AWS page :)

Amazing video!

This is exactly what ive been looking for! Thanks man! I appreciate you showing multiple options on how to do something

I love your videos and have subscribed. your info is very helpful! Some of the best I have found!
I hope I am not out of place suggesting something: the vocal recording is quite "boomy" as they say in the recording business which can make it hard to listen on some systems and there are easy fixes: grab a free EQ (like Audacity) and make a cut in the 100-300 Hz range. If you want to sound great on YT: 4db cut at 125Hz, 2db boost at 2k Hz and high pass filter below 100 Hz. Also, experiment with speaking from 6-12 inches from your mic to avoid the "proximity effect" which is mostly an issue for deeper voices with better quality mics.

A note on that: I love cognito, it‘s a great service which fulfills all my needs. However, I have 2 pain-points which are quite annoying to get by:
- documention is (as for most services) absolute hell. it‘s all there - somewhere. you just need to guess the right words to find what you want to achieve in the docs or somewhere at stackoverflow
- it‘s not fast. logging in or refreshing a session sometimes takes a few seconds which can be painfully blocking.

additionally, aws-amplify was such an overkill for me that I decided to just go with the aws-sdk and it‘s js-client libs. they‘re much more straight forward and don‘t require a whole bootstrap setup.

still, great videos like yours are an immense help for beginners and also advancaed users as well.

Great video. Content sugestion: create a passwordless authentication with Cognito using Triggers.

is there any option of getting a token besides the URL, Actually I fetch the access token from the URL and then validate it from my frontend(js) via API headers but it has a security flaw, upon login, it shows my Access token in the URL or is there any option to hide it

u should upload more videos on cognito with lab

If only cognito would support localisation of the hosted UI.

It is 2022 and they support only the English language!??

It is sad that cognito does not have support for flutter web. Luckly I understand enough angular to make my frontend but Flutter would be easier for me

Great work!
In the use case, how does your own backend server validate Cognito token?

Awesome video. Came in timely manner as we're working on adding Cognito to our app :)

I like cognito, and feel like I will still choose it over auth0 , but it still has poor documentation, you should talk about sessions and how cognito fails with access and refresh tokens as well as how it becomes expensive when going through different scenarios say adding flags to validate flows and challenges if you are working on more complex user authentication ( say multiple customers, invites, etc etc.). Still it is a great video introducing Cognito and your work is always amazing. I feel that you could do a couple of videos, based on your experience mentioning challenges faced with some AWS services that maybe a small project or company won`t face but that huge products and highly available systems will definitely do 👍 Again, awesome work and keep it going!

Literally couldn't have had better time in making this video! We just started using cognito at work!

Great video! Can you make a video on Elastic Beanstalk flask api vs lambda for the same? How many concurrent requests can ELB actually handle?

Good to know.
