The short version

  • Each has a real cost: 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.; Semgrep free tier caps out at 10 contributors and 10 repositories.
  • They diverge on capability: Google Authenticator covers TOTP code generation, Semgrep covers Static code scanning.
  • Prices and features above were last checked on 1 September 2026.

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.

Semgrep

  • Free tier caps out at 10 contributors and 10 repositories.
  • Secrets scanning is priced as a separate module ($15/contributor) from Code and Supply Chain.
  • Self-managed repositories and custom CI/CD require the Enterprise tier.
  • AI credits are limited per tier and additional usage requires upgrading.
