Unlike the world of banks, it’s only you who can access the funds in your SOL wallet! This is the main feature of storing the assets in a blockchain. Only one who has the private key can perform and sign a transaction within your wallet accounts. Your key is stored at your device and is only accessible via your PIN or fingerprint. So if you lose the phone - nobody can extract it from there and access your money, but you can restore the access via a verification SMS.
