Start with the most common causes before resetting the wallet, restoring from a recovery phrase, or trusting a support message.
The local Phantom password, browser profile, phone lock, or recovery phrase is being confused
The wallet is still accessible on another trusted browser profile or mobile device
A browser reset, phone change, app reinstall, update, or storage issue changed local access
The recovery phrase is needed for restore on a new trusted device
The app source or support path is unsafe and requesting private wallet data
A fake helper is offering account unlock, wallet validation, or remote access
A Phantom restore can show a different Solana address or incomplete asset view when the browser profile, account order, mobile backup context, hidden tokens, NFT filters, or Solana indexing state differs
A Phantom browser, extension, or mobile update can reload the wallet, reset connected-app sessions, or show stale Solana token and NFT data until the app refreshes
