App with Phonegap get different fingerprint every time

[igorosabel]

Hi!

I'm making an app for iPhone using Phonegap and I liked your library so I wanted to use it to identify people and remember their logins.

The problem is that every time I run the app it gets me different fingerprints. I haven't done anything weird, on XCode I run the app and gives me a value. I stop it, run it again and it gives me a different value.

Thanks!

Hi again! I just found out that the fingerprint is getting different every time because the user agent in Phonegap apps have a different number attached every time:

Mozilla/5.0 (iPhone; CPU iPhone OS 8_0_2 like Mac OS X) AppleWebKit/600.1.4 (KHTML, like Gecko) Mobile/12A405 (358060448)
Mozilla/5.0 (iPhone; CPU iPhone OS 8_0_2 like Mac OS X) AppleWebKit/600.1.4 (KHTML, like Gecko) Mobile/12A405 (358060448)
Mozilla/5.0 (iPhone; CPU iPhone OS 8_0_2 like Mac OS X) AppleWebKit/600.1.4 (KHTML, like Gecko) Mobile/12A405 (384315344)

I still don't know why they do this, but taking the browser agent from the fingerprint "ecuation" kind of solves the issue.

A guy from cordova project comments it here: https://issues.apache.org/jira/browse/CB-5420?focusedCommentId=13830117&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13830117

Thanks!
