I need it only selectively. The SimpleLogin MASK/icon covers my 1Password icon. I need a way to turn this ON only when I need it.. for now I'll have to remove.

Convenient and simple addon

This app is worthy of gold ...

When you go to a hotel desk, Do they give you a key that opens all doors ( ie. accounts ) ?
Then why should you not treat your email the same way ??
You should install different locks for all accounts or at the least, categories of accounts ...

Simple to use but very efficient and effective.
Browser extension makes it always at the Ready ...
Don't waste your time with free alternatives, you will end up here anyway ... like Tina, " she's simply the best "
2 years later ... nothing more to add ! sad truth is everyone should use this app ... Yes, Really

It's super useful but the extension fetches its content each time you open the popup, which takes a sec and makes for an unfluent experience.

Works really well and does everything it promises. The only glitch is that some websites won't accept the "@simplelogin.com" domain. If that happens, try the alternate "@slmails.com". Or try the "totally random alias" feature that omits the website name from the alias. I don't know how the websites are screening SLMAILS. Do they have a way to check for valid email addresses in real time? If that is the case, it may be necessary to use an alias that you already created some minutes ago, or used at least once before.

Very convenient and easy to use.
