1Password vs Bitwarden

Which one to pick

1Password logoPick 1Password if

  • You want the Secret Key: a copied vault can't be attacked with your master password alone
  • You'd rather pay for a polished app than run anything yourself
  • You want named third-party pentests every year (Anvil Secure in 2024, Secfault Security in 2023)
