Pros
- Secure and smooth integration across multiple devices.
- Works cross-platform on iOS and Android, supporting local network backup and token export/import.
- Easy to set up and functions as advertised, maintaining security without complexity.
- Open source with code that can be audited for security.
- Effective replacement for other 2FA apps like Authy, with good backup and export features.
Cons
- Frequently fails to send push notifications to the phone, causing delays or no response.
- Requires linking and approving on a mobile phone every time, which users find inconvenient.
- Extension does not generate or autofill codes directly; it depends on the mobile app for code approval, leading some users to find it redundant.
- Onboarding and pairing process can be complex and sometimes does not work properly.
- Lack of desktop-only usage; mobile phone is always required, limiting usability.

Extension safety
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk
impact extension cannot do much harms, whereas a high risk impact extension can do a lot of
damage like stealing your password, bypassing your security settings, and accessing your
personal data. High risk impact extensions are not necessarily malicious. However, if they
do turn malicious, they can be very harmful.
2FAS Auth - Two Factor Authentication requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
