# Sign in flow

|
## tl;dr
|
|
In general, at first we try to encrypt realm database using password
|
|
and then proceed with the rest of operations. We do not wait for
|
|
`Statusgo.Login` callback in order to show `:home` screen with chats
|
|
as this call may add more than 1s to the process.
|
|
|
|
|
|
|
|
