Biometrics are preferred over traditional passwords

• Passwords are more unique
  

• Easier and faster to access
  
• You can't "forget" your fingerprint
  

• The ROI will easily pay for the implementation
  

• By 2020, there will be 300 billion traditional passwords
  
• 95 traditional credentials and passwords are stolen every second
  
• 200 000 web logins get stolen every week. This includes traditional passwords found on websites and mobile apps
  
• 3 out of every 7 people will have their passwords stolen at some point in their lives
  

• Stolen passwords will cost an estimated $6 trillion in damage by 2021 
  

• Top researchers and scientists took 5 weeks to physically trick a hand scanner. 5 weeks!
  
• The accuracy of fingerprint scanning  for most systems is well beyond 95%
  
• Accuracy increases exponentially with more fingers -- Three fingers will result in an 100% accuracy
  
• No two sets of biometric data is, or will ever be alike
  

1. He provides zero sources to back up any of his factual claims. You should view his arguments extremely skeptically because of this. Compound this with him not unveiling all his constructive arguments in the first round, thus giving me less time/space to make responses to them, and you should be extremely doubtful of the validity of his claims. 
   
2. This debate is on which is better for society overall.
   
3. The debate assumes we use only one type of security rather than layering things. You should look at the advantages of a type of security on it's own rather than combined with something else.
   

1. Prefer my evidence for the lack of security of biometrics over his 'III' argument since I've cited my evidence validating my claim. He's yet to show any kind of evidence backing up his claims. 
   
2. Prefer my analysis on the ease of hacking biometrics over his (unsourced) stats of how many traditional passwords are stolen - I've outlined the specific method and how easy it is to do. This is something that any common person can do, which magnifies the threat and impact to hacking biometric locks.
   

1. There's no source to this claim. 
   
2. There's no context behind this claim - what is costing money? Who's money is being lost? How is money being lost?
   
3. This claim is intentionally misleading - it's an estimate of the future, and doesn't make any claim as to damage done in the present.
   
4. This claim doesn't make sense - how does me stealing my buddy's Twitter password cost someone/thing $6 trillion?

not unveiling all his constructive arguments in the first round

So long as I don't tell anyone else what this password is, it's private - only I have access to it.

Barring sophisticated hacking skills, which your average person doesn't have access to, this password is secure.

We leave our fingerprint on everything we touch.

scientists in China discovered a cheap and effective way to bypass the 'aliveness detection'

Ease of hacking biometrics [..] I've outlined the specific method and how easy it is to do. [..] Any common person can do ...

This claim doesn't make sense - how does me stealing my buddy's Twitter password cost someone/thing $6 trillion?

The damage of a stolen password is relatively simple to fix - reset your password.

I only have one fingerprint, or one eye

Extend my argument that it's super unfair for him to hold arguments in reserve to the end of the debate because that gives me less time to be able to make responses to them so that we can, y'know, debate. His only response is that he didn't set up any explicit structure to the debate so it's okay but that doesn't address the fairness concern. Fairness is important because it's impossible to determine a winner and loser if the debate is skewed. Don't let him make new constructive arguments in the last round of the debate as I can't make new arguments to respond to them. 

Also, don't allow him to get away with posting sources in the comments. This lets him bypass the 5k character limit that he set up when he made the debate. And don't let him say I can just do the same thing as I already had to spend room in my last round listing sources where I could've made more arguments so the damage is done. This is a game-over mistake because it means literally none of his arguments have any evidence to back it up - I'm the only one with valid cited sources.

- Hacking -

• Hackers exist -
  

1. At best this is non-unique. He's not denying that biometrics are hackable as well, so whether or not something can be hacked is a wash.
   
2. At worst, it's a reason to vote neg rather than pro. Not everyone has the capabilities to hack a phone or computer. But anyone can go to Walmart and pick up some cheap glasses. This makes the risk of hacking far higher for biometrics which is a net negative.
   

• Biometrics are harder to hack -
  

1. Look back to my source. The most difficult part that they listed was that "you don’t want to wake up the victim"[1]. Hardly the elaborate story he wants to paint.
   
2. Even if what he says is true, his own sources list ways to bypass this problem, such as "master prints" that can unlock a majority of devices and attacks on the databases housing the biometric data[3][4]. If anything this is a reason to vote neg rather than aff, because his arguments provide the illusion of security rather than actual protection, which could lead to people being more careless with their devices, making it easier for would-be thieves.

biometrics are used to protect far more important things in scope than simple passwords

biometrics are used to protect far more important things in scope than simple passwords, meaning that the damages from hacking are far more severe

There's literally nothing in this article that specifies damages from traditional passwords, rather it only says its damages from "cybercrime"

you can't just get a new eye or a new finger

don't let him make a new response in the final round [...] Aff tries to get away with a lot of unfair stuff

Passwords are the weak link [...] they're hard for you to keep track of

IT needs to verify the identity [...] track down all the places where the password needs to be changed

• Large companies spend $70 per password reset
  
• Microsoft's IT spends $2 million a month helping people (and their own employees) to change their passwords
  

but ultimately the [traditional] password appears doomed in the face of a truly 21st century alternative - TNW

1. He's not giving you any reasons why these arguments matter. There's no impact to be found here.
   
2. Forgetting your password is good as it forces you to reset your password, which increases account security and makes it harder for your account to be hacked. This means you vote for me rather than him off this argument.
   
3. The harms of having your account hacked outweigh the cost a company has to pay to reset someone's password.
   

1. This is a completely new argument and should've been made a lot earlier if he wanted it to have any credence.
   
2. Wut? No I don't. You can control+f his statement ("Because they are proven to be better for the companies that use them.") and you won't find it anywhere in my rounds. Nor is this what my source says.
