If you know nothing about password managers to the point where you're asking a question like this, you should at least start with a cloud based manager.
Also if you use a reputable company, you're pretty safe. BitWarden is great. LastPass has been absolute bottom of the barrel for years now after LogMeIn bought them.
What do you mean by being able to see the time instantly?
My miband has an always on OLED display (if you want it) or the ability to have lift to wake with all of the different delays and sensitivities.
If anything, I'd say my miband shows the time quicker. My watch is also LED, not OLED, which is a bummer.
I may be weird, but I hate my WearOS devices. I highly prefer a Mi Band.
It gives me all of the same info my WearOS watch does (heart rate, spo2, sleep tracking, steps, app notifications, timers, alarms, phone call alerts, weather, etc) but is a more comfortable compact package, and the battery lasts 5+ days vs 18-25 hours. Not to mention the price is usually 5-15x cheaper.
I know I'm a minority, but I genuinely don't understand why people want a WearOS watch?
Ya, my mi band has that, too. It's called always on display. Since it's OLED, it doesn't cause a ton of battery drain, and I can see the time without lifting it.
