Currently you're forced to have e.g. the same account
security settings wherever you access LastPass.
Profiles could enable you to have different requirements @ different locations (e.g. using IP ranges or something)...
- Home: MP only.
- Work: MP + OTP via Yubikey.
- Friends house: MP + OTP via SMS.
- Public: MP + OTP via Yubikey + OTP via SMS. (Your default maximum security setup.)
