Answer first
Use a file exported by the account owner instead of connecting live account credentials.
A follower comparison does not require a third-party service to know the Instagram password.
Context before action
A site that imitates an Instagram login screen creates avoidable credential risk.
Mutual status can change after the export, so verify accounts that matter.
Read the relationship state correctly
The check compares two present-tense sets. “Outgoing only” says where the username appears now; it says nothing by itself about intent or history.
Never enter an Instagram password or verification code into an independent follower analyzer.
Choose the next step
Review the relevant group and leave intentional one-way relationships alone.
