From Couchbase version 5.0, buckets no longer use bucket-level passwords and you must access the bucket using a user and password that you must create in the Couchbase Web Console, if it does not already exist. The user must have the same name as the bucket that you want to use in Image Modified, and you must enter the mandatory password as the bucket password, which you specify in the Couchbase profile as the Bucket Name and Bucket Password. For further information on the Couchbase profile, see 8.5 Couchbase Profile.

Note!
You do not need to change anything in the couchbase profile and settings to use Ephemeral buckets.
However, Image Modifieduses Couchbase secondary indexes, so if you use Ephemeral buckets theIndex Storage Mode should be set to memory-optimized.
