Reactor users should be aware of a new, secure login experience.
If you’re connecting from outside an approved network, you’ll now be able to sign in using email verification. Users will see two login prompts with this experience (once to pass the network gate, and again to log into Chainalysis products). We hope that this makes access to Reactor easier while continuing to ensure the highest level of protection for your information. See this document for more information: https://developers.chainalysis.com/resources/docs/reactor-email-verification/overview
