密碼輸入上的 UX

Hacker News 上看到「Gmail password first character is case insensitive on mobile device (support.google.com)」這篇,在講密碼輸入上的 UX。

在 Hacker News 上的討論看到這則:

This is a well-understood feature. Facebook does the same thing[0].

Quote:

Facebook actually accepts three forms of your password:

* Your original password.

* Your original password with the first letter capitalized. This is only for mobile devices, which sometimes capitalize the first character of a word.

* Your original password with the case reversed, for those with a caps lock key on.

接受三種密碼,第一種是完全正確的密碼,第二種是第一個字如果是大寫時的密碼 (在行動裝置上可能的行為),第三種是大小寫全部相反的密碼,這在沒注意到 caps lock 時會發生。

強度不會削弱太多,但對於 user experience 好很多的設計。
