2! Authenticator is a web browser extension that allows you to instantly see two-factor authentication codes (TOTP based) for login use on many major websites and apps.

Hard at work on your desktop or laptop computer? Now your two-factor codes are just a click away in your browser!  It is designed to be compatible with the other Authenticator © apps, and its use is similar. 

Easy to Use
Add your two-factor codes by copying and pasting a QR Code image, drag-n-drop a QR code image, scanning a code with your webcam, or manually entering a two-factor key. Now your specific, time based, two-factor code for your online account is just a single click away.

Private and Secure
The extension is built with security and privacy in mind.  Data is never shared with any other entities and a network connection is not required for the use of this extension, with the exception of registering for and the validating of paid features.  

Paid Features
For a one time fee of USD $2.99 you may encrypt your data, transfer f lock your codes, and get data backup for life.  

Encryption of Data (Paid Feature)
There is the ability to encrypt and lock your data using the latest encryption standards (AES-GCM) with a pin or password. (DO NOT FORGET/LOSE YOUR PIN/PASSWORD!  For security purposes, it is NOT possible to recover your data if your PIN/PASSWORD is lost.)

Data Backup and Transfer (Paid Feature)
Never lose your two-factor codes again!  You may backup all of your two-factor codes in a secure format that may be restored at a later time.  Backup your two-factor codes to a hard drive or cloud service of your choice. Additionally, you may choose to display an individual account’s QR code allowing each two-factor code to be transferred to another device.

Known issues:
* Transfering codes from other authenticator apps may be limited: Poor webcam resolution may reduce the number of accounts that may be transferred at one time.
