Hi can you help me to create api for email confirmation
Thanku

Thank you brother. I have submitted your link, as one of the big help I gain in completing my project. And It would help to have an update, as Google does not support the “Less secure app” option anymore.

Can you provide your github link

there is no more possibility to activate less secure app, is there any solutions?

Never seem anyone f rails before

thx for the instructions, got it working thx to you. For anyone not getting email, make sure you check your spam folder :)

What settings I could possibly have wrong if my gmail doesn't send emails ?

Thanks for this video! You help me so much! Everything is working! But I install gem 'figaro', and add variables GMAIL_USERNAME
GMAIL_PASSWORD in config/application.yml

I followed exact steps using rails 6.0. Everything look exactly same on the log file as well using gmail account. Tried mutiple times but not receiving any email.....any other possibility??
