Amazon Cognito vs. Microsoft Entra External ID

Well Suited

1. B2C mobile and web apps with a high number of users.
2. Cheaper and cost-effective.
3. If the other pieces of the infra are already using AWS services like Lambda, S3, Pinpoint, etc.

Not Suited For:

1. Advanced use-cases (Biometrics based authentication) Email, and other MFA channels.
2. For any use-cases needing SCIM.
3. Customized flows of SSO, and MFA will need a layer on Lambda and other AWS services.

In our organisation we use Microsoft Entra External ID primarily to enable non-attenders to remotely login to our tenant and access pre-prepared educational resources. As well as access to tutors, pupils can also communicate with centralised staff who can support them to gain an education. Utilising our external tenant configuration we can develop and deploy our own in house apps to unpin this support intervention.

• Strong integration with React.js and client-side applications
• Easy to bridge Cognito identities with the rest of the AWS ecosystem
• Easy to store user profile data directly in Cognito rather than having to build additional services/endpoints
• Easy integration with AWS Lambda to extend and add sophistication to the service

• One of the things that Microsoft Entra External ID does really well is creating user logins, accounts and profile. It is very easy to create them, manage them and delete them. It is fast and reliant.
• Limit access or authorization feature. We can allow different levels of authorization and access. So that not all the employees would have access to all the data. Only some relaible employees would have access and power to change anything.
• Mutli factor authentication feature is also a really good feature to secure data. Even overseas vendors need MFS to login which gives double protection to our data.

• Amazon Cognito has a bit of a learning curve. You need to learn its concepts and terminology. The documentation does not describe some topics comprehensively.
• Some Console screens would benefit from improved search and filtering options.
• When another AWS product (e.g., SageMaker) configures Cognito on your behalf, it is not clear what you're getting. For example, the expiration of a temporary password was configured but never communicated.

• Troubleshooting diagnostic logs effectively requires VS Code
• Group and role management requires additional effort
• The programming model (XML) could use some developer experience love

Amazon Cognito is easy to use and implement if you don't need to implement custom policies. But if your security team requires something outside the box, then implementation becomes complicated and you risk wasting time. There is no option for customizable regex for passwords, which is a major deficiency. The standard password policy, allow to choose the length of the password, if it should contains at least one number, one special character, one uppercase letter and one lowercase letter.

Microsoft Entra External ID is an all round solid product, and certainly delivers the solution to our needs well. Through use we found that Pupil's become 'experts in avoidance', if they can forget their login details or indeed their device used for MFA, they will and then use that as the excuse for not accessing/completing their assignments. If more MFA options were available (such as delegated MFA) this would really help iron out our entire end user experiences

Community support is excellent, many times even better and quicker then the offical AWS support. I really cannot recommend community support enough! Apart from that the service is relativily easy to use and does not have a huge learning curve. Examples are easy to follow and will help you start using the service.

They are ideal tools to create a secure and unique login experience for our applications. Thanks to its API authorization, Amazon Cognito ensures connections to applications that are secure.It is easy to use and provides easy access to files and applications that you need to complete your goal.

I really enjoy how simple it is to connect this Active Directory with other Microsoft Products to collaborate with colleagues and clients.

• ROI is great for Amazon Cognito Overall.
• It is included in the AWS Free Tier so you can use it for a good amount without paying, so the software can be tested beforehand.
• The paid pricing is also affordable, so a positive impact on ROI.

• Having monthly active users billing was cost-effective.
• Helped with the IT support that was already managing the Azure platform of the company; this helped to manage the costs better and optimize them.
