Migrating to Auth0.js v9

Auth0.js v9 has been improved to operate with enhanced security and removes dependencies that have been deprecated as per Auth0's roadmap. In some cases, these security enhancements may impact application behavior when upgrading from an earlier versions of auth0.js.

Should I migrate to v9?

Everyone should migrate to v9. All previous versions are deprecated as of April 1, 2018, and will at some point cease to work after this date. For clients who use Auth0.js within an Auth0 login page, this migration is recommended; for client applications with Auth0.js embedded within them, this migration is mandatory.
