Hello,
We were wondering what the best practice is for migrating user ids. Currently, we are using a system of randomly generated user ids (~20 characters). I know that auth0 generates an identifier that looks like this 102437854499766869014 (21 characters).
In terms of security, we looked into uuidv4 which looks like ad076419-fde7-4940-b18c-1d86607491f0 and we weren’t sure what the best practices are for migrating these ids.
Should we migrate the current ids (~20 characters) into auth0 and use auth0’s generated ids in the future or keep our own set of ids?
Thanks!
