Recovery is designed to be simple. If you used Social Login (Google or Apple) to create your Slush account, you can recover your wallet by logging back in with the same social account.
If you use a Passphrase account, you must have your 12-word recovery phrase or private key. To reconnect the account, choose "Import Existing Account" on the welcome screen and enter your passphrase or private key.
Note: Slush is non-custodial. If you lose your 12-word recovery phrase and private key, your funds cannot be recovered.
