After changing battery, all applications requesting confirmation of passwords.

[AC Question]

So, after changing the battery on the phone, it may have taken me a while to confirm the log-in pattern on start up. When I eventually confirmed the log-in pattern, the phone asked if I would like to start up in Safe Mode. This is the first time I have seen a Safe Mode option on Android. In addition, several apps asked me to confirm the passwords. So, did I just give up passwords to some entity or is this a real thing?

Thanks in advance for your help!
