Gembok Authenticator is software based (virtual) authenticator to generate 2-Steps authentication token using browser. It is written in HTML and Javascript so it should works on Google Chrome, Firefox, Safari and other browsers. It uses simple JSON file to store all data which needed to generate the token.
Gembok Authenticator uses the same algorithm as most software based authenticator such as Google Authenticator. Based on my personal limited test using various services such as Twitter and AWS I found no issue.
Gembok Authenticator uses following library.

First thing you need to do to start using Gembok Authenticator is to create JSON file containing token's information.
Here is an example of JSON file. Copy JSON string below and then save it to your computer as .json extension.
[
{
"provider": "Google",
"description": "Main account",
"secret": "I5XW6Z3MMUQG2YLJNYQGCY3D",
"period": 30,
"digits": 6,
"algorithm": "SHA1",
"indicatorColor": "red"
},
{
"provider": "AWS",
"description": "Root account ([email protected])",
"secret": "IFLVG4TPN52GCY3D",
"indicatorColor": "orange"
},
{
"provider": "Twitter",
"description": "[email protected]",
"secret": "KR3WS5DUMVZC4Y3PNVVG62DO",
"indicatorColor": "#1DA1F2"
},
{
"provider": "Facebook",
"description": "Foo account",
"secret": "IZQWGZLCN5XWWLTD",
"indicatorColor": "#4267B2"
}
]The only required attributes are "provider" and "secret" the rest are optional.
Save the JSON file and then use Open File... menu to load the file. You should now see 4 items being displayed.
You can also encrypt JSON file using AES-256-CBC and Gembok Authenticator automatically ask you passphrase and try to decrypt the file automatically. Here is an example of above JSON encrypted with AES-256-CBC with passphrase "gembok-authenticator".
