Will iOS 13 ever support iPhone 6?

iOS 13 is available on iPhone 6s or later (including iPhone SE). Here’s the full list of confirmed devices that can run iOS 13: iPod touch (7th gen) iPhone 6s & iPhone 6s Plus.

Is iPhone 6 still secure?

iPhone 6 series phones are pretty much consistent with the newer iPhones and can update to iOS 13, except for the iPhone 6. Only 6s and above can upgrade higher than iOS 12. You can’t go wrong with an iPhone, and at such a low price compared to newer models, the iPhone 6 is a safe bet.
