I was literally flashing something ten minutes before and then I tried going back to recovery and there were no directory so I then rebooted it says I need a password... But I never one made a password, I didn't even know there was passwords for recovery

Never mind... Just kept rebooting then eventually the problem was gone... How can I set a password for bootloader and recovery... Just wondering if it's even possible

You can't set a password for either (well, not to my knowledge!)

Even with a password we can fastboot flash new images.
Team Win explains this on their website.

Yes and no.. Actually we can lock the bootloader so fastboot flash wont work.... All we need is for the recovery password to block the following to secure your data (on the nexus 5):
  • Mount of external (OTG) media
  • adb access
  • file manager capabilities

This would mean you can still boot into recovery and flash / backup (although not to removable media) until you went into a security menu to "unlock recovery". This would even mean that your automated jobs can still occur without having to face a "boot password". The password could be stored on /sdcard in clear test and there could be an option to delete the password incase you forgot it in this same recovery menu, which also wipes the device.

recovery is the only weak point of my device.

Sure, Samsung's Odin will get round this password on their devices as the BL is not locked but any device with a locked bootloader (locakbale bootloader) will benefit.

Another caveat is that this is not to prevent the device being wiped.... unlocking the bootloader will wipe the device, and this is what I want. I don't care about getting the phone back as much as I would care about securing my data. Its all backed up. Nothing is lost. I just might not want someone else getting access to it.

Although this is beyond the extent of my knowledge to achieve, I don't think it would be hard for anyone who knows what they're doing with code.

Do u mean that you always have a locked BL?

Thanks for your feedback but one thing remains the same IMHO. Of course we can lock the BL but a thief can unlock it then flash factory images. No more custom recovery, passwords...
I'm not talking about the user data but to be able for a thieft to use a device even with locked stuff.

I'm just talking about data security. That is my only concern. Devices are replaceable. Unlock bootloader, data wiped. fine!

Oh thanks everyone, I just wouldn't want a theif to use a phone they don't deserve, pretty much the only security on my phone to not go to bootloader is for no power menu on my lockscreen but you could probably use adb to get through
