Microsoft Entra External ID offers scalability and flexibility but faces latency issues and lacks some authentication methods.
As I continuously add users, customers, and refactor for other applications in Auth0 Platform, it supports my application growth efficiently.

Room For Improvement

Auth0 needs better flexibility, pricing, multi-tenancy, API management, on-premises options, UI, customization, documentation, and authorization features.
Microsoft Entra External ID needs cost reduction, faster sync, better security, improved SSO, UI, integration, support, and pricing clarity.
The only area for improvement is that Auth0 Platform cannot handle requests for developing APIs for legacy systems, such as mainframe models, where ForgeRock and IBM Security Verify Access can be utilized.
Senior Manager And Vice President at a tech vendor with 10,001+ employees
We must subscribe to a major plan to access most of their features. While this works well for larger companies, for small companies or those conducting POCs, this affects our budget allocation for other initiatives.
Lead Engineer at a tech vendor with 11-50 employees
Auth0 Platform's documentation is excellent, their support organization is excellent, their code is robust, and it's certified as secure.
Principal Consultant at Building Block Technologies Inc.

Setup Cost

Enterprise buyers view Auth0 as cost-effective, though specific features or scaling can increase costs; licensing offers clarity and tiers.
Microsoft Entra External ID pricing varies, cost-effective for some, expensive for others, challenging cloud transition impacts evaluation.
A downside I remember mentioning is that pricing can be high at scale, though that is not a product issue; it relates more to the nature of large enterprise solutions.
Partner Account Manager at a wholesaler/distributor with 51-200 employees
Considering the amount of features I use, such as multi-factor authentication, it is affordable and comparatively less for the features it is giving compared to other existing platforms.
Associate Software Engineer at a computer software company with 201-500 employees
They provide a large free tier that is beneficial to companies with applications just starting to scale their user base.
Principal Consultant at Building Block Technologies Inc.

Valuable Features

Auth0 excels in scalability, security, and integration, with features like SSO, MFA, and universal login enhancing user experience.

Being able to execute custom code snippets within Auth0 Platform to set different access levels or provide messages to users who lack access to requested pages, along with tracking and notifications, is very beneficial.

Identity workflows have transformed how we secure logins and manage user access daily
There are different elements to the best features Auth0 Platform offers, and I have touched on them, particularly the ability to help applications authenticate and authorize their users and manage their identities. A big point is identity federation, allowing connections across multiple identity providers, enabling users to log in using existing accounts due to databases and enterprise identity systems. A strong security feature is provided, particularly with their MFA, multi-factor authentication, which includes bot detection and brute-force protection, along with breached password detection, which is really good as an added extra. Auth0 Platform has positively impacted our organization, particularly in terms of usability. While we are not selling it directly, I find the platform easy to use for authenticating different users. Our own services team handles the implementation, so I cannot comment on the ease of that process. However, whenever we have had contracts and bids to roll out services, it has been really easy. We have seen improved security due to the implementation of Auth0 Platform. User management, such as creating and deleting users, is all about enhancing the user experience, which is massive. We assist with password resets and account linking. The time to implement is shorter, and we maintain a consistent user experience with a secure login flow, benefiting from a faster implementation due to the universal login, providing a hosted login page customizable by developers.

Offers strong identity unification but needs better customization
Microsoft Entra External ID can be improved with additional features, specifically customizable flexibility and a customizable user interface for the login dialog. Currently, the login dialog has very limited customization options, which only include font styles, colors, text messages, or brand icons. Last month, Entra ID introduced some customizable features in their login dialog, but this does not apply to Microsoft Entra External ID, indicating a significant gap between the two. In theory, Entra External ID can support many external identity providers where custom login dialogs could be integrated, potentially via SSO feature coordination, although I have not yet confirmed this. Hence, enhanced customizable login options and the ability to use attribute password logins are critical features that are required for Microsoft Entra External ID to gain dominance in the authentication market.
