As of today, if you search the net, you can find a large number of people having trouble with the iOS version of Safari on their iPad and iPhones. The nature of the problem is that Safari won’t save log-ins and passwords — and when you go to another page, even if you keep the tab open, bam, you’re logged out. Same thing if you use the device’s button to go do something else for a moment, open another tab, etc. It’s really annoying.
So if you go hunting for answers to this annoying behavior from Apple, they recommend you check your keychain (Settings, iCloud, Keychain, On) But that doesn’t solve the problem. Apple also recommends that you make sure that Safari has been set to save passwords (Settings, Safari, Passwords & AutoFill, Names and Passwords, On) That is required, but odds are you’ve looked at this already and it is set correctly — and Safari still refuses to save the state of your log-ins and passwords.
This is what I found: In Safari, by which I mean when Safari is actually running, there’s an icon at the top right that looks like a very thin pair of boxes overlapping one another. This is the Choose Tab icon. Right? It’s there so you can choose tabs, obviously. Right? Right? Well, yes. And no. Touch that little bugger, and take a look at the top line. See that word, Private up there? Does it have a white box around it right now? If so, touch that. The white box should go away. If so, Safari will now save your log-ins and passwords just like you expect it to.
It could easily have happened that on entry to this tab-choosing interface, you accidentally hit that “Private” button, turning on the feature where Safari keeps no cookies or other information. Unfortunately, this behavior cripples any web site’s ability to track who you are and if you’re logged in, so if you tough this button by accident, Safari is now mysteriously crippled.
Apple’s iOS has a few really troublesome drawbacks, and one of them is that they don’t put application settings within the applications, they put them in System Settings, except, of course, when they do put them in the application — as we have seen here. This kind of user interface inconsistency can separate functionality from application and when they do both (have controls in Settings and within the application), it’s very difficult to know where to look, much less what you’re looking for, when a complex application like Safari misbehaves.
So there you have it. I hope this helped you resolve any password / log-in problems you were having with the iOS version of Safari.
