Turo for sharing cars. It’s car rentals but weird since you’re borrowing other people’s cars.
Kyte is in a similar vein for on demand cars via app, but it functions similar to a traditional car rental in every other way. Though they’re a baby company so they might not be a good Uber comparison yet.
My personal experience has been pretty good and the prices are very competitive, but we’ll see how they survive when the VC money runs out.
There is nothing you can do about the unsuccessful logins to your email address. My original email address has been in so many hacks and it’s always being brute forced by hackers outside the US.
You already have MFA, so the only other thing I can think of is to have an incredibly long random password on your account and make sure the “forgot my password” recovery flows don’t have any easy way to bypass. Things like another email address as a backup that’s less secure, being able to guess your personal details based on past hacks, easily guessable/researchable security questions (make these random or nonsensical if possible, or don’t put details from security questions in social media) could be used to gain access, even with MFA. And finally, secure your password manager in a similar manner.
