New A16 Galaxy asks for Password (opens in new tab)

Hello guys, I was trying to transfer data from my Samsung A50 Android to A16 Android\. I recharged both phones and again tried to transfer\. Now, the A16 is asking for a Password, so I used the Password for the A50, but it does not work\. Suspecting that data has been transferred to the A16 at first attempt, I went to ‘Find my Phone’ Both phones show in Find my Phone\. How can Unlock the A16, please?\. Thank you\.
