@Sasha888 Welcome to the forum!
The only method would be to press the Esc.
There is also a relevant feature request topic: Ability to move/drag the BW shield icon (of the inline autofill menu) out of the way.
However, I am curious about why you are manually typing passwords into the password fields, instead of generating and/or autofilling the password using Bitwarden. Could you please explain your use-case?
It’s unclear what you are describing. Where and how are you manually editing or creating vault items? Are you doing this in the Web Vault?
And what do you mean by “my default password for Bitwarden”? There is only one Bitwarden password (your master password), which is usually not saved anywhere (unless you have deliberately created a vault item for storing the master password — if you have done this, please confirm).
My guess is that you are simultaneously using the Bitwarden Web Vault and the Bitwarden browser extension, and that you have configured things in such a way that edits made in the Web Vault are being captured by the browser extension. If I am correct, then the easiest fix may be to open your browser extension, go to Settings >Notifications > Excluded Domains, click ⊕ Add domain, then enter vault.bitwarden.com and click Save.
