      • I was on locked booatloader running Oreo 8.0. I had clean installed Oreo 8.0 from OnePlus recovery fastboot mode. To root I unlocked the bootloader, flashed TWRP Oreo version and when I tried to log into TWRP it would ask for password.

          • I had the first time I tried rooting my fully set up Oreo OP3. After the initial password prompt in TWRP I thought it might be a ROM issue so I cleared everything and started with a clean stock install of Oreo with no password/fingerprint protection at all but the issue still persisted.

            I was finally able to get everything to work by doing it all at once. Fastboot sideload Oreo 8.0 using stock recovery, unlock bootloader, flash TWRP and then SuperSU all in one go.
