My phone is Huawei P9 Gold and my Tablet is Samsung Galaxy S 10.1.
I woke up this morning and tried to connect my phone first to wifi but it won't connect. So I restarted my phone and it still won't work. I reconnect my phone to wifi but it says "Incorrect password", so I typed my password and it's still says the same thing. I'm very sure that the password I typed was correct. Also, the same thing happened to my tablet.

1st step: Reboot the router by unplugging it for 20 seconds and plugging it back in. When it's back up, retest your devices.
I noticed you didn't say, "... my Wi-Fi." If you're the one paying for Internet service, use a short CAT 5e cable to connect to your router and visit the Wi-Fi settings to make sure they're unchanged/correct. If you're using someone else's Internet service you'll need to speak with them to see if they changed the Wi-Fi password.

Someone must have changed the wifi password on the router. Check with other members of the house, if no-one owns up you should be able to log into the router and set the password to one of your choice. You would need a laptop or desktop connected by an ethernet cable. As a last resort you may have to set the router to defaults, the wifi password would then be the one on a sticker on the router as it came from the factory but you would also have to enter additional details that your ISP needs so you would probably need to contact your ISP

maybe you should call whoever your internet provider is
