Identity exposure often grows from repeated identifiers that are easy to correlate across platforms, not just one isolated event.

High-friction controls worth adopting:

  • Use distinct usernames for public, financial, and private contexts.
  • Separate email aliases by purpose.
  • Minimize one-number-for-everything patterns.

Keeping these separate reduces the damage from any single exposure and makes it harder for anyone to connect your accounts and identities.
