Different accounts under different brokerages and banks

Hi - another question as I am on this investment journey.

Is it common to have different accounts all over the place? (Maybe this is standard i dont know)

For example, i want to set up a Roth IRA and invest in mutual funds with Vanguard. I also want to open a HYSA and was looking at Peak Bank. I will ALSO have a separate 401k going at my job and a checking account at my local credit union.. is this pretty normal? I‘m assuming as long as you stay organized and know what’s what it doesn’t matter much? Thanks!
