It can take days. I changed all of them once I bought the password manager. Though the fact that they are so much stronger and also completely different from every other password means that if one site gets hacked the damage is limited. For many people they have the same password for everything. Most of mine are 20 digits long but I am slowly upgrading them to as strong as allowed. My wifi is 50 digits long which is overkill but will keep out all but the most determined and skilled hacker.
