+## Reconcile profile conflicts
+You might encounter a profile with a consent value of `conflict` if one of your end users consents to different categories on different devices or if two distinct IDs are linked to one Unify profile.

+
+### Device-level conflict
+A device conflict occurs when consent for one user ID is collected from two distinct devices. This conflict is automatically resolved to accept consent from the most recent interaction. 
+
+For example, if a user first didn't consent to advertising on their mobile phone, and then later consented to advertising on their desktop computer, their consent for the `advertising` category would be set to `true`.

+
+### Profile-level conflict
+A profile-level conflict occurs when two distinct userIDs with different consent preferences are merged into one Unify profile. A profile-level conflict can also occur when a userID and an anonymousID (one without a linked userID) are linked to the same profile by an external ID, like an email address or phone number, and the consent preferences of both profiles do not match.

+
+To avoid profile-level conflicts, Segment recommends that you take the following steps:
+1. **Use `user_id` to identify a profile or person.** Using other identifiers, like a phone number, email, or `anonymous_id`, can result in a profile-level conflict. 
+2. **Set `user_id` as the highest priority identifier in the [Identity Resolution](/docs/unify/identity-resolution/identity-resolution-settings/#priority) settings.**
+3. **Maintain the default `reset()` behavior.** When a user explicitly logs out of your application, call `analytics.reset()` to prevent any further event activity from being associated with the logged out user and generate a new `anonymousId` for subsequent activity (until the user logs in again).
