I like it for a number of reasons (other wallet apps can meet these bars, as well):
1) It is very cross-platform. It works on iOS, Android, MacOS, and Windows. I believe that it is also Linux-ready.
2) It has the ability to sequester groups of passwords into "vaults," that can then be assigned in different configurations, for different accounts. This way, the Treasurer gets the banking login, and whatnot, but the Webmaster never sees them, and Treasurer never sees the CP login.
3) It seems to support a whole bunch of TFA.
4) It syncs over everything, and helps to enforce password hygiene.
It supports many more kinds of secure data than passwords and credit cards. It has specific entry types for bank accounts, passports, reward programs, software licenses, and so on.
It also has lots of built in analysis tools for determining:
- which of your passwords are reused, weak, or present in online password dumps
- what websites can have 2FA enabled on them
As well as the ability to store entire documents in vaults.
Been using 1Password since 2008 and it's the only software of its kind I recommend to anyone on any platform.
There’s some nice “sanity checks” on all passwords, manual or generated, like reused password warnings and by default it checks your logins at haveibeenpwned, which is a nice to have.
Are there advantages of using it over Apple's built in keychain?
Would appreciate if someone who has used/uses 1Password could comment on this.
