Still trying to figure out what happened. Moved about 0.2 BTC to my blockchain.com wallet, and within 30 minute, it was gone.
I've moved on to using a hardware wallet now.
- Whenever I try to log in to my blockchain.com account, I get an email verification (2FA). This was working properly, at least whenever I log in. I never got an email about someone else trying to log in.
- Whenever I receive/send BTC at this wallet, I get a text notification. I did not get a text when BTC was received. I did not get a text when the BTC was sent.
- My recovery phrase is kept offline.
