How do you sign into i phone without passcode?

You can't, if a passcode has been set up. If this were possible, anyone who picked up your phone would have complete access to all of your data.

Are you really saying here that you have forgotten your passcode? If that is the case......

If your iPhone is running iOS 15.2 or higher........(it appears that it might be).......you can use the instructions linked just below which will not require the use of a Mac or PC:

How to reset your iPhone, iPad, or iPod touch when you forgot your passcode - Apple Support

If you are not sure which operating system is installed on your iPhone, please use the link below, which will require the use of a Mac or PC.

If you have a backup of the phone, you can use the backup to restore the data on the phone during the new setup.

If you could bypass the screen lock passcode, there would be no point in even having passcodes. The only way to reset the screen lock passcode is to erase the device. There is no alternate mechanism.

Erasing is required to ensure that no one can gain access to any iOS or iPadOS device, with intact data still on it, without knowing the passcode. Thus iOS and iPadOS are designed so that erasing the device is the only means of resetting a forgotten screen lock passcode.
