A small analysis of statistics for 4 months at the inputs of users to one Belarusian resource through the following form:
Total login attempts: 615,000 Total Unique Successful Entries: 76,000 Cookie expiration date: 2 months Analyzed period: 4 months
General alignment of unique successful entries in the context of Email / password vs. Openid
Analysis of login attempts
Email / password: 94.97%, of which:
invalid login: 25.99% (of these, 38.56% were most likely entered not by email, i.e. without "@")
invalid password: 36.71%
OpenID: 5.03%, of which:
“Missing openid.mode” error: 21.46%
Error “Discovery failed: Bad HTTP response”: 20.60%
other errors: 2.58%
Popularity OpenID Providers
Email Providers Popularity
Mail.Ru in statistics also includes @ bk.ru, list .ru, inbox .ru; similarly with the others (@ ya.ru, @ googlemail.com)
If a user is registered and has an email / password pair in the Email provider, which is also an OpenID provider, he can log in to his profile via email / password and OpenID (which is converted to email format) of his choice. This is done because, as a rule, users do not remember how they entered before and when there was no common entrance they were often confused.
A feature of Bynet is that only about a third of our users have external Internet enabled. So perhaps OpenID could be even more popular.
