Within Particle social logins SDKs, users can set up two different passwords. Each serves a distinct purpose in securing accounts and authorizing actions.

​
Master Password

  • Purpose: Encrypts and backs up the user’s local MPC key share.
  • Ownership: Known only to the user — Particle never stores it.
  • Recovery: Cannot be reset or recovered if forgotten.
  • Usage: Provides an additional encryption layer for secure wallet recovery across devices.
If the user forgets the Master Password, the encrypted key shard becomes inaccessible.

​
Payment Password

  • Purpose: Used as a second verification step before signing transactions.
  • Flexibility: Can be disabled or reset by the user at any time.
  • Experience: Adds a layer of security without affecting wallet recovery.
