Passcode requirement change? Malware?

[weareborg]

Hi everyone, thanks in advance.
This morning when I turned on my phone, I had a strange popup message that said "you must change your passcode within 60 minutes." I bit and changed my (4 digit) code in the box, but I became concerned it might be malware and also changed my code manually. The only reason I currently have to think it could be malware is because it was an odd message. As of this writing, it hasn't happened again. I couldn't find much on Google.
Some details:
I am running a 6+ with iOS 8.1. I have not downloaded any 3rd party apps or clicked any links (I honestly only have "popular" apps on my phone since I recently received it). My phone is in no way linked to any work profiles. I do have a gmail account synced to the phone. I'm not jailbroken.
I think that is all the relavant info- thanks.

Do you have any other mail or calendar accounts on the phone?

I don't think I am given a timeframe to change the code, but I have to change mine every 60 days because I am hooked into Microsoft Exchange e-mail through my work. If I remove that account from email, I don't ever have to change my passcode again.

No. This is a completely personal use phone, and I've only had it for about 2 weeks. My (one) gmail account is all I have synced.

A cursory Google search suggested that it could be a software bug? Or possibly "too simple passcode" but I've always used a 4 digit password (and used this passcode for 2 weeks) so I'm not sure why an alert would be triggered now. I have downloaded anything on my phone for about 1 week.

Well, even a "popular" app might have something hinky going on.

Was this phone ever restored from a previous back-up that might have been associated with a company or school? Maybe an old mobile device management profile installed. Or from one of the apps (eg. seen network monitoring software install profiles, so, maybe some app plopped something on).

Believe installed profiles can be seen under Settings > General

Generally, that message is coming from some sort of device management profile.

Yeah good points, although profile was the first thing I checked. There's no profile section for me under settings-general, and I've never had any phone associated with a management profile.

When I set up the phone, I set it up as a "new iPhone", not a backup.

Very weird, if it happens again I will screenshot it. I have a new passcode so hopefully that solves my problems...

Accounts (eg mail) added to your phone can enforce passcode policies. One of the companies I work with do this, and after setting up email and calendars, I was forced to ensure I have 6+digit pincode. No big deal if you have Touch ID

It's likely an account had just changed their policy.

It would have to be an exchange account for that to work.
