I don't understand why we hash data like passwords. I know it's harder to steal hashed data rather than just plain text, and it takes longer, but once one of those public hashing methods gets cracked, lots of that data's gonna be stolen. And by the time there's another method, you're gonna have (possibly) things like account hijacking, credit card fraud, etc. With technology exponentially growing in power, It doesn't seem that secure. In other words, why is hashing so important if it'll be cracked sooner or later?Edit: Sorry if I'm sounding like a noob, I'm new to databases and want to make a login system, and thought of this along the way.
For the same reason you lock your doors when you are gone: It makes it more difficult for someone to steal from you. Additionally, there are steps you can take when "encrypting" data (salting for example - I think you were probably talking about hashing passwords, which is different than encrypting.) that would make it more difficult to decrypt. You couldn't simply, say, compare against a rainbow table looking for known values.

Encryption is a way of keeping your data safe and confidential as it is sent over the internet. Whenever you send personal information across the internet, be it passwords, credit card information or personal contact details, encryption stops others from seeing what you are doing.
Regarding password managers, my feeling is that some commentators are missing the mark with blanket assessments because they are not including the threat landscape or the other controls one might use.
2FA or MFA does not really matter when it comes to password database security as long as the design is the 2nd factor secret is independent of the cryptographic key mixture. All it requires is capturing the decryption keep and it is game over. The 2nd or nth factor only serves to further authenticate but the main point is capturing the cryptographic key is the main goal. In the context of a network password manager, it opens a lot more questions and doubts than offline password managers.
Ease of use can be improved by GUI designs and user interaction and portability of solutions can be done with portable offline devices in your own control. A less tech savy person carry a portable executable of an offline password manager with good GUI design to ease usage. 2ff7e9595c
