I really like 1Password as both my PW manager and OTP generator. PWs and OTPs get synced across devices so I never worry about losing my phone and getting locked out of any 2FA sites. On iOS as well as desktop, 1Password can auto-fill passwords and OTP codes. Highly recommend.
I use Carfax. You can create an account and self-report services. Some shops will automatically report to Carfax on your behalf, but most don’t, and I certainly have to enter my own DIY work manually.
This came in clutch when I sold my last car private party because I was able to print out the Carfax for my vehicle and it included my self-reported records as well, the buyer loved it.
