## 説明

This plugin activates easy self-service two-factor (or multi-factor) authentication
logins for you and all your users.

CryptoPhoto is the world’s easiest-to-use, fastest, and most secure two-factor (
and optionally multi-factor) authentication. Logins are usually as fast and easy
as “one tap”, and no training is needed.

After installation, users will see a new “CryptoPhoto” dashboard menu item, which
they can use themselves to activate and download printable tokens, or install the
CryptoPhoto app to connect their smartphones or tablets (iOS, Android, WindowsPhone,
and Blackberry).

Our user-experience testing was conducted using year-1 schoolchildren. They all 
successfully logged in without us giving them any instructions. CryptoPhoto is way
easier to use, than it is to describe – but here’s how it works anyway:

After users activate CryptoPhoto, they will see a photo during their logins, and
at the same time, their phone (or tablet) will beep and show them a collection of
photos too. (if they don’t have any smart devices, or have lost their phone, they
use their downloaded paper token instead). To complete their login, they simply 
tap the one on their phone that matches the login one (or type the codes if they
don’t have a phone, or don’t have mobile coverage). This is why CryptoPhoto is currently
the worlds most secure two-factor-authentication – the photos create “mutual authentication”(
which blocks phishing and Man-in-the-middle MitM attacks) – nobody else does this.

CryptoPhoto also combats malware, viruses, advanced-persistent-threats (APT’s), 
trojans, keyloggers, phishing and spoof/impostor/fake websites, vishing (telephone
phishing), shoulder-surfing attacks, careless password choices by end users, password
re-use problems (eg: passwords stolen from other web sites won’t compromise CryptoPhoto
users), confidence tricks, and more: we simultaneously protect our users against
more threats than any competing solution (and, in fact, against more threats than
all competing solutions combined).

CryptoPhoto works with or without smartphones/tablets, works home and abroad, online
and offline, and keeps working (securely) even when users loose their phones/tablets.
CryptoPhoto is the industries lowest-support-required two-factor-authentication 
solution: you do not need to hire a support team to mange users enrollments and 
issues (like bypasses and re-enrollment when users loose their phones/tokens).

To securely install the CryptoPhoto plugin, you will have to follow some steps to
generate unique keys for your installation etc. The steps are on in our [Cryptophoto Installation guide](https://cryptophoto.com/info/admin)

  1. What do I do if the Configuration test prompts me the “Error: Unknown error”
message?

You might want to check the Apache error log for more details on the error. If nothing
relevant is logged there or you do not have access to the error log, feel free to
contact the CryptoPhoto technical support team at [CryptoPhoto Tech Support](https://ja.wordpress.org/plugins/cryptophoto-two-and-multi-factor-authentication/Tech@CryptoPhoto.com?output_format=md)
who can trace and diagnose your error.

  2. What happens if I change the initial salt

This is not a catastrophe. It’s not reversible though, all your user’s CryptoPhoto
settings will be reset, meaning that they will have to re-enable CryptoPhoto authentication
for their account and download new tokens. Their previous tokens will be rendered
useless and they will have to download new ones.
