Open-source expectations
If source transparency matters to you, compare the codebase, release cadence, and whether the app clearly documents its backup model.
Browser extension tradeoff
Extensions can make login faster, but they also blur the line between a local authenticator and a browser-integrated workflow. Decide whether that convenience fits the accounts you protect.
Recovery requirements
A good alternative should explain how secrets move to a new phone, whether the restore path is encrypted, and what happens if you uninstall the old app too soon.
Comparison checklist
- Verify whether the alternative includes a documented export path.
- Check if desktop or browser integration is required for your workflow.
- Keep backup codes outside the authenticator app itself.
Watch-outs
- Open-source status does not guarantee a simple recovery story.
- Browser extension support can change the threat model for shared devices.
