Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Google Authenticator

  • Enabling cloud sync moves the security boundary for your 2FA codes to your Google account, so a compromised Google account can expose the same codes syncing was meant to protect.
  • It has no built-in backup export in a portable format, so moving away from Google Authenticator to another app usually means resetting 2FA on every individual service.
  • It lacks organisational features such as folders, search or notes that some competing authenticator apps offer for people managing many accounts.
  • There is no desktop app, so codes must be read off a phone screen when logging in from a computer.
  • If sync is off and the phone is lost without a separate backup, all codes are unrecoverable and every linked account needs its 2FA reset through account recovery.

Vault

  • Vault 1.15.0 and later is licensed under the Business Source License 1.1, not an OSI open source licence, with IBM Corporation as licensor
  • The Additional Use Grant forbids offering Vault to third parties on a hosted or embedded basis in a paid product that competes with IBM's paid versions of Vault
  • Each version only converts to MPL 2.0 four years after that version is published, and the Change Date is tracked per version
  • Replication, HSM support, namespaces, performance standby nodes, FIPS builds, control group authorisation, multi-factor authentication, secrets sync and lease count quotas all require a Vault Enterprise licence
  • A Vault Enterprise licence must be applied to the cluster before any Enterprise feature can be used
