 ## changes in this  version
 
+* Added support for Two factor authentication (2FA). When detecting 2FA in an user account, Socializer will switch automatically to alternative tokens. There is some work to authorize kate's tokens with 2FA, but currently it doesn't work fully. ([#13,](https://code.manuelcortez.net/manuelcortez/socializer/issues/13))
 * tokens generated by socializer will never expire. ([#3,](https://code.manuelcortez.net/manuelcortez/socializer/issues/3))
 * In order to use all methods available in VK, socializer will use tokens of kate mobile for Android. It means you may receive an email by saying that you've authorised Kate for accessing your account from an Android device.
 * Audio albums are loaded correctly.
