Modern identity access has unified customer logins and strengthened risk‑based protection
Auth0 Platform from Okta, which is for access management and single sign-on, is basically for dividing modern IM into categories. The first is workforce identity, meaning SSO and access management solutions for users, partners, and temporary employees, which is catered by a traditional Okta Platform. Customer identity speaks about internet application customers, such as logging into an FMCG application through mobile or laptop applications like Flipkart, Amazon, and Alibaba.com. If security is needed for these applications, it is called customer identity and access management solution, CIAM, and requires a different tool because the user base will be in millions or billions. For instance, banking apps and airline applications fall under CIAM solutions, and Auth0 Platform will be implemented for these requirements. Most integrations will not be done by traditional connectors but by exchanging metadata between the application and Auth0 Platform. Once metadata is exchanged, certificate information and cryptographic keys are also exchanged, making transactions secure. Different methodologies for onboarding users are available, including bulk onboarding and risk score features. If someone logs into a banking app normally from the UK, but they log in from Namibia after stealing a mobile phone, the application detects this change of location as a zero trust model. Policies such as restricting app access based on location can also be implemented using Auth0 Platform, along with self-service user registration features similar to opening a bank account. Universal login, while I do not think it has a major impact, allows a seamless experience by authenticating multiple app logins from one entry point, which would be particularly useful in healthcare applications. Auth0 Platform is quite affordable compared to IBM Security Access Verify, which is on the higher end. ForgeRock and Okta are in the same bucket for pricing.

Questions from the Community

What do you like most about Auth0?
It is very scalable because it provides a new environment for companies based on their number of users and other factors. The tool can take a lot of users.
What is your experience regarding pricing and costs for Auth0?
The cost of the solution itself was cost-effective enough that I didn't even need to compare it with EntraID.
What needs improvement with Auth0?
I do not think there are any improvements needed for Auth0, other than maybe making it more visible to beginners. Auth0 could be made more accessible to beginners.
