Needs consent
Yes
Does the MUID cookie require consent?
MUID is used for advertising, so under the GDPR and the ePrivacy rules it may only be set after the visitor has agreed. Showing a banner is not enough on its own: the cookie must not be set before the visitor clicks accept.
Does your site set MUID before consent?
A free scan loads your site the way a new visitor sees it and lists every cookie that is set before anyone has said yes, MUID included.
How to put MUID behind consent
Remove the Microsoft Advertising (Bing) snippet from your site and add your Microsoft Advertising (Bing) ID under Integrations in Consentify instead. Consentify then loads Microsoft Advertising (Bing) only after the visitor has accepted advertising, so MUID is never set before consent.
