Chosen Solution

I’ve chosen the options to unlock my phone with fingerprint or password. I basically have only used the fingerprint so far, but after a restart of the phone I’m now required to submit the password which I have forgotten. How can I proceed, is factory reset the only option left? :/

Yeah, if it shows reactivation lock on in the download mode menu then you will need to factory reset the phone via recovery as you can’t flash custom files with reactivation lock on which would allow you to remove the password via custom recovery. You can check this by turning off the phone then holding power + volume down + home until you see the download mode prompt screen, then use volume buttons to enter download mode. Look at text at top right for reactivation lock info. To get out of download mode hold the same keys again for 10-15 seconds. The process of bypassing the screen lock involves flashing a custom recovery, typically TWRP then booting into the recovery, mounting the system partition, and using the built in file manager to delete the following files
