The awkward moment you set a new password and don't remember it anymore on the next day.

Use a password manager. You don't even have to know what the password is.

Create a algorithm to build passwords based off service name so even if you forget you can just run it to figure it out.

I did this with my Mac's firmware password once. I discovered, after some very simple googling, that the firmware was crackable by removing RAM and got around it. Didn't bother with a password after that.

@nerd-san that's an interesting idea, but I see some problems.

1) You'd have to hide access to that algorithm, so no one else can just use it to get your password
2) if you're on your phone or at someone else's computer you can't get your password

You could the generator available online but then you still would need at least one password to access it.

Just some thoughts..

@simeg
I mean algorithm as in just a set process for setting passwords.

This isn't what i do, but as an example:
1. Start with random phrase you will use for every password for length.
(pizzahatstastebest)
2. Then multiply the number value of first 2 letters of the service.( for devRant 4×5 = 20)
3. A symbol that you always use. (%)
4. The current year so you remember to change passwords occasionally.

So for devrant your password would be

pizzahatstastebest20%2016

Long, so hard to crack, somewhat random per service, so less vulnerable if one password is hacked, and easy to remember.

@nerd-san aha, yeah I have a system like that for my passwords but not as complex. It works great!
