Start with the most common causes before resetting the wallet, restoring from a recovery phrase, or trusting a support message.
The wrong Chrome or Brave profile, disabled extension permission, popup blocker, privacy shield, stale cache, or conflicting wallet extension is affecting MetaMask
The selected network, custom RPC, account, token visibility, or bridge status does not match the expected balance
A restore re-created the first account but additional accounts, imported private-key accounts, or hardware wallet accounts were not re-added
The extension and mobile app are showing different accounts, browser profiles, manually imported tokens, or networks after a restore or update
A browser or app update changed local state before backup readiness was checked
A browser update or extension reload reset permissions, locked popups, disconnected sites, or left stale cache/RPC state that needs a refresh
A fake extension, cloned download, support DM, or wallet validation page is asking for the Secret Recovery Phrase
