Kiwi flowers look exactly like you’d think they would. #woah
Woke up this morning bleeding from the neck. Surprise #vampire attack?
Partner’s husband dropped car at garage.
Garage calls me to say it’s ready.
“My partner will pick it up,” I say.
“The other guy said his wife would pick it up?” they reply.
“Yeah, that’s right.”

2004 called, @virginmedia. They asked me to remind you that maximum password lengths and prohibiting pasting makes your security worse, not better. @PWTooStrong
In more detail:
- Why would you set an upper limit on security? It can’t be for space/capacity reasons because you’re hashing my password anyway in accordance with best security practice, right? (Right?)
- Why would you exclude spaces, punctuation, and other “special” characters? If you’re afraid of injection attacks, you’re doing escaping wrong (and again: aren’t you hashing anyway?). Or are you just afraid that one of your users might pick a strong password? Same for the “starts with a letter” limitation.
- Composition rules like “doesn’t contain the same character twice in a row” reflects wooly thinking on that part of your IT team: you’re saying for example that “abababab” is more-secure than “abccefgh”. Consider using exclusion lists/blacklists for known-compromised/common passwords e.g. with HaveIBeenPwned and/or use entropy-based rather than composition-based rules e.g. with zxcvbn.
- Disallowing pasting into password fields does nothing to prevent brute-force/automated attacks but frustrates users who use password managers (by forcing them to retype their passwords, you may actually be reducing their security as well as increasing the likelihood of mistakes) and can have an impact on accessibility too.
- Counterarguments I anticipate: (a) it’s for your security – no it’s not; go read any of the literature from the last decade and a half, (b) it’s necessary for integration with a legacy system – that doesn’t fill me with confidence: if your legacy system is reducing your security, you need to update or replace your legacy system or else you’re setting yourself up to be the next Marriott, Equifax, or Friend Finder Network.
- It’s definitely not the first time you’ve been told. Get your act together.
