How Many Secondary Accounts Can Be Linked

[rueben.tiow]

Problem statement

This article clarifies the limit of the number of additional secondary accounts for a user.

Solution

There is no hard limit on the number of secondary accounts that can be added, but there are limitations on the size of the user’s metadata (for example, if adding a secondary account’s metadata to the primary during linking - this is not done automatically) and if additional claims are being injected into ID and Access tokens then this could also similarly run into token size limitations.

• Also, Actions can only persist an additional 32kB of metadata per login transaction, so these would need to be taken into account if trying to operate with profiles with large metadata - please see Actions Limitations.
