Our large bank recently changed their Android app so you can no longer paste a password. 
This is a MAJOR problem if you're using a password manager. I don't type passwords any more.
I contacted them (via their Twitter support) and explained that this is a security fallacy that pasting is dangerous.
Also, you can still paste a password when you login on their web site.
I wanted to mention that to them but was afraid they'd stop it there too.
May Only Prove That The Bank Devs/ Contractors Are Clueless
To me this only exposes the fact that the developers or security contractors or whatever actually have NO CLUE about WHAT SAFE PRACTICES are.
They could even remove copy functionality separately and I would be ok with that. But how could the paste functionality EVER be an exposure? They are just so clueless. 
EDIT 09/24/2018
Look what I found from the National Cyber Security Centre:
Let them paste passwords - NCSC Site[^]
And it provides additional links as to why pasting should be allowed.
I tweeted this to the bank site.
EDIT 2 09/24/2018
Check out this Wired article and the associated quote:
https://www.wired.com/2015/07/websites-please-stop-blocking-password-managers-2015/[^]
Wired: But accounts aren't broken into by repetitive copy and pasting. One hacker told WIRED that disabling paste on a webpage does not stop him from using automated tools to speedily gain access to users’ accounts.

A large bank will have a dedicated team of security idiots people who will listen to the latest gossip, read what is shoved under their nose and get the developers to implement the policies they think up. If there is nothing to change they will think up something to do, a team has to justify his existence.
You cannot blame the developers for such idiocy, they may even have protested the change.

That's a great explanation and exactly what I thought.

Very good point and I guess I was really thinking of the security team...not the devs.
Over all it is just craziness. Making things unusable so the security team can feel like they're doing something important.

As much as I denigrate them for some of their blunders I would not have their job for quids. Trying to keep in front of the bastards attempting to hack the banks must be a nightmare.

Yeah, I can agree with that. But, it seems like they'd focus on creating the smallest exposed footprint and work on that instead of things like the paste feature.
I can't actually imagine the security people explaining how the paste feature could be dangerous.
Security guy: So, yes, we must remove the user's ability to paste into the pwd field because it is extremely dangerous. It's huge security hole.
Bank's IT Manager: Can you give me 2 examples of how pasting into that field would be dangerous?
Security guy: Well, they could paste special extended characters, maybe?
Bank IT Manager: Shouldn't the back-end handle that?
Security guy: well, they could paste um...errrr...well, pasting is just bad that's all. Andy why would any legitimate user want to paste? I think only crackers paste.

I know of a certain national bank that only allows letters and numbers. No punctuation or special characters. I swear they actually WANT their customers to have their accounts ripped off.

It really does feel that way in some of these cases, because the logic they use is so bad.
I also know that many only allow your password to be only 16 chars in length (or shorter) even though password length is the one thing that actually strengthens passwords. It's crazy.

And that is a perfect additional example of the contrast you find. Some sites remove functionality that is completely safe, other sites just open the door for the thieves.

I completely understand your frustration. I also hate websites (mostly banks) that disable pasting on their websites and just for gigs, they'll need me to type certain things like account numbers, BSB code, etc. twice.
I use Don't F*** With Paste[^] extension on Chrome and tell them straight off. I'll copy, paste, cut, do whatever the hell I want on my computer. I will treat any entity that assumes an intellectual high-ground (while knowing next to nothing about security in reality) with great disdain, and will override their "security rules" with extreme prejudice.
I'd have rambled on a bit more if this was the soapbox, but the kid sister is watching so I'll go play merry-go-round instead.

I think disabling paste in password boxes are a great idea when it comes to securing customers, their data and money. Please tell me what you think of me now (give your best shot!). 
BTW, thanks for that extension.

Raj is (or was?) a nice guy.
Come to think of it, with Aussies and their compulsive behaviour to shorten up words, you might as well be referred to as Raj.

It's kind of why I said it's likely to be "another Raj". That, and the outsourcing to India.

Thanks! It is very refreshing to hear from others who really loathe these bad policies too.

Does your password manager not offer an option to simulate keystrokes to enter your password, rather than blindly relying on the clipboard?
(I have no idea - I don't use a password manager - at least nothing that'll try to type in anything for me out of "convenience")

Simulating keystrokes is more difficult in an Android app and it is the Android app that they (bank) removed the paste ability from.

I see.
As far as I'm concerned...considering the number of Android devices out there that have known exploits that'll never be patched, because OEMs can't be bothered...all banks should block Android altogether.
I rarely side with banks, but Android device vendors are downright irresponsible. IMNSHO.

Ok, I can accept that Android devices are vulnerable. That's fine.
But, then, the resolution for the bank is not to disallow pasting...it is to disallow the use of an Android device altogether. In other words, they shouldn't have ever created an Android app in the first place. I would accept that decision more readily than the blocking paste solution.
But then that would mean they needed to block the web site from Android Web browsers too. 
It would be interesting and funny if the bank just came out and said, "Sorry, you can only use our e-banking via Apple devices."

Write a piece for the local newspaper, based on facts, explaining how the bank either does not take security seriously, or is run by incompetents.
And be sure to name the bank by name

Exactly why I have not written the article.
However, did you see the update to my post?
I found an article from the National Cyber Security Centre which also has links to Troy Hunt's explanation on why pasting is safe and important and it has a link to a Wired article 2015 which has very interesting info on why pasting should(must) be available in apps.
