There was a problem hiding this comment.
Note that random_bytes(4) only has 32 bits of entropy, which is less than the previous call to uniqid() with $more_entropy set to true. This should use at least random_bytes(8) for 64 bits of entropy and ideally random_bytes(16) for 128 bits (the latter would result in a slightly longer output of 32 characters instead of 23 for uniqid).

maybe we should use the initial suggestion from the issue and use a UUID instead (see #57872)
