Suddenly today, when I restarted my phone and typed in my password, it said that my password was not recognised.
I typed many many times as it was definitely the correct password (no caps lock etc) but it would not detect it as being correct.
This is the first time this has ever happened, I have not installed any new software or anything recently so I am really confused.
Now the password is detected as correct, but it will tell me "try again in 30 seconds". I have waited over an hour and it still will not work.
Please please help me to not have to do a hard reset and lose all my data! I do not have a Samsung Find my phone account registered to this phone, so cannot do that.
Yes - at first it would not let me because it needed a password to turn the phone off.
But I selected restart, and it restarted, but no difference. I tried a soft reset too, no help.

Sign in using your Google login details that you also used on your locked phone.
In the ADM interface, select the device you need to unlock (if it isn’t already selected).
In the appearing window, enter a temporary password. You don’t have to enter a recovery message. Now click ‘Lock’ again.
If it was successful, you should see a confirmation below the box with the buttons Ring, Lock and Erase.
On your phone you should now see a password field in which you should enter the temporary password. This should unlock your phone.
Now, before you go on with your life, go to your phone’s lock screen settings and disable the temporary password.
