I know it may be added as a security measure like scam or buy-sell accounts, etc. But when a person sees that message, he or she may get a bad impression of the account. He or she may not trust the person, or the account may not get much interaction. Because I chanced password, now I'm tagged with that message.
Password reset isn't in anyway a bad thing except there's something one is hiding from the public glare. We do it on other sites we visit whenever we suspect something fishy with our accounts. Once I get at OTP (I ain't talking about here) on any site I use but didn't ask for it, I know someone what's to access my account without my knowledge. The next thing I do is reset my password. It simply tells you that they've broken your password but couldn't get pass the 2FA on that account. If with time you feel your password has become too easy, it's better changing it. It doesn't mean it's a bought or compromised account.
1. I'm a custom ROM user. So I have to factory reset my phone in order to test the new build. I recently flashed several Roms to test.
(Clean flash is mandatory to avoid bugs)
2. I don't have any second devices. So I can't just have it logged in on another device.
You should make it a priority to get a second device then so you can separate your ROM duties from every other ones where you don't have to constantly reset to test stuff.
3. I easily forget. One time I even forgot or confused my username because I used 0 (zero) instead of o in my username.
Solve the problem by writing out your username on a piece of paper, if you don't have a digital notebook.
4. I always think of BTT as a highly valuable platform. I'm in fear that my BTT account would get compromised someday if I saved my password in an online place.
It's not a wise thing to do, whether with BTT or any other site. The old fashioned way of paper and pen still remains the best method of saving passwords to the best of my perspicacity, anyway.
